          Revision Standard - Superseded.<br />\n
          Metal-enclosed medium voltage switchgear (ME), which can contain either drawout electrically operated circuit breakers or stationary electrically operated circuit breakers in individual three-pole grounded metal compartments, is covered. Further, metal-clad switchgear (MC) is compartmentalized to isolate all components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltage levels for metal-clad switchgear (MC) range from 5 kV through 38 kV with main bus continuous current ratings of 1200 A, 2000 A, and 3000 A. Rated maximum voltage levels for station-type cubicle switchgear (SC) range from 15.5 kV through 72.5 kV with main bus continuous current ratings of 2000 A, 3000 A, 4000 A, and 5000 A. ME switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices as necessary. Service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application are discussed.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad and station-type cubicle switchgear containing, but not limited to, such devices as power circuit breakers; other interrupting devices; switches; control; instrumentation and metering; and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution.<br />\n
          This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies rated above 1000 V. It applies to equipment that is part of primary and secondary unit substations. It does not include gas insulated substation equipments.<br />\n
          In this standard metal-clad switchgear shall be called MC switchgear, and station-type cubicle switchgear shall be called SC switchgear. Whenever the data covers both types of equipments, they shall be called ME switchgear.

          Revision Standard - Superseded.<br />\n
          Metal-enclosed medium voltage switchgear (ME), which can contain either drawout electrically operated circuit breakers or stationary electrically operated circuit breakers in individual three-pole grounded metal compartments, is covered. Further, metal-clad switchgear (MC) is compartmentalized to isolate all components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltage levels for metal-clad switchgear (MC) range from 5 kV through 38 kV with main bus continuous current ratings of 1200 A, 2000 A, and 3000 A. Rated maximum voltage levels for station-type cubicle switchgear (SC) range from 15.5 kV through 72.5 kV with main bus continuous current ratings of 2000 A, 3000 A, 4000 A, and 5000 A. ME switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices as necessary. Service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application are discussed.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad and station-type cubicle switchgear containing, but not limited to, such devices as power circuit breakers; other interrupting devices; switches; control; instrumentation and metering; and protective and regulating equipment.

          Switchgear Assemblies including Metal-Enclosed Bus (1974 Consolidated Edition). Other types of<br />\n
          equipment previously included in ANSI / IEEE C37.20-1969 (R 1981) will now be incorporated in<br />\n
          separate publications.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad and station-type cubicle switchgear containing but not limited to such devices as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution.<br />\n
          This standard is concerned with enclosed, rather than open, switchgear assemblies rated above 1OOOV. It includes equipments that are part of primary and secondary unit substations.<br />\n
          It does not include gas insulated substation equipments.<br />\n
          In this standard metalclad switchgear shall be called MC switchgear and station type cubicle<br />\n

The switchgear contains, but is not limited to, such devices as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution. This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies rated above 1000 V ac. Included is equipment that is part of primary and secondary unit substations. Gas-insulated substation equipment is not included. In this standard, metal-clad switchgear is denoted MC switchgear.<br />\n
          This standard provides information essential to the designing and testing of MC switchgear. Included herein are preferred ratings, required design test procedures, and acceptance criteria. A detailed description of construction requirements, including required functional performance features, structural materials, insulation, and interlocking, is provided. Additionally, information on equipment application with respect to operating conditions, dielectric capabilities, and detailed application information regarding continuous current capabilities under differing ambient temperature conditions and application involving short-term overloading is included.

          Revision Standard - Superseded.<br />\n
          Metal-clad (MC) medium-voltage switchgear that contains drawout electrically operated circuit breakers is covered. MC switchgear is compartmentalized to isolate components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltage levels for metal-clad switchgear range from 4.76 kV to 38 kV with main bus continuous current ratings of 1200 A, 2000 A, 3000 A, and 4000 A. MC switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices, as necessary. Service conditions, ratings, temperature limitations and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and applications are discussed.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad switchgear containing, but not limited to, such devices as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution. This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies rated above 1000 V ac. Included is equipment that is part of primary and secondary unit substations. Gas insulated substation equipment is not included. In this standard, metal-clad switchgear will be called MC switchgear.<br />\n
          This standard provides information essential to designing and testing of metal-clad switchgear. Included herein are preferred ratings, required design test procedures, and acceptance criteria. A detailed description of construction requirements; including required functional performance features, structural materials, insulation, and interlocking is provided. Additionally, information on equipment application with respect to operating conditions, dielectric capabilities, and detailed application information regarding continuous current capabilities under differing ambient temperature conditions and application involving short-term overloading is included.

          Metal-enclosed medium voltage switchgear (ME), which can contain either drawout electrically operated circuit breakers or stationary electrically operated circuit breakers in individual three-pole grounded metal compartments, is covered. Further, metal-clad switchgear (MC) is compartmentalized to isolate all components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltage levels for metal-clad switchgear (MC) range from 5 kV through 38 kV with main bus continuous current ratings of 1200 A, 2000 A, and 3000 A. Rated maximum voltage levels for station-type cubicle switchgear (SC) range from 15.5 kV through 72.5 kV with main bus continuous current ratings of 2000 A, 3000 A, 4000 A, and 5000 A. ME switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices as necessary. Service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application are discussed.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad (MC) switchgear containing, but not limited to, devices such as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution.<br />\n
          This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies rated above 1000 V ac. Included is equipment that is part of primary and secondary unit substations. Gas insulated substation equipment is not included.

          Revision Standard - Superseded.<br />\n
          Metal-enclosed medium voltage switchgear (ME), which can contain either drawout electrically operated circuit breakers or stationary electrically operated circuit breakers in individual three-pole grounded metal compartments, is covered. Further, metal-clad switchgear (MC) is compartmentalized to isolate all components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltage levels for metal-clad switchgear (MC) range from 5 kV through 38 kV with main bus continuous current ratings of 1200 A, 2000 A, and 3000 A. Rated maximum voltage levels for station-type cubicle switchgear (SC) range from 15.5 kV through 72.5 kV with main bus continuous current ratings of 2000 A, 3000 A, 4000 A, and 5000 A. ME switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices as necessary. Service conditions, ratings, temperature limitations, and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application are discussed.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad and station-type cubicle switchgear containing, but not limited to, such devices as power circuit breakers; other interrupting devices; switches; control; instrumentation and metering; and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution.<br />\n
          This standard is concerned with enclosed, rather than open, indoor and outdoor switchgear assemblies rated above 1000 V. It applies to equipment that is part of primary and secondary unit substations. It does not include gas insulated substation equipments.<br />\n
          In this standard metal-clad switchgear shall be called MC switchgear, and station-type cubicle switchgear shall be called SC switchgear. Whenever the data covers both types of equipments, they shall be called ME switchgear.

          New IEEE Standard - Superseded.<br />\n
          This standard includes only the requirements for metal- clad and station-type cubicle switchgear.<br />\n
          These requirements were previously a part of ANSI/IEEE C37.20-1969 (R 1981), IEEE Standard for<br />\n
          Switchgear Assemblies including Metal-Enclosed Bus (1974 Consolidated Edition). Other types of<br />\n
          equipment previously included in ANSI / IEEE C37.20-1969 (R 1981) will now be incorporated in<br />\n
          separate publications.<br />\n
          \t\t\t\t<br />\n
          This standard covers metal-clad and station-type cubicle switchgear containing but not limited to such devices as power circuit breakers, other interrupting devices, switches, control, instrumentation and metering, and protective and regulating equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, and transmission and distribution.<br />\n
          This standard is concerned with enclosed, rather than open, switchgear assemblies rated above 1OOOV. It includes equipments that are part of primary and secondary unit substations.<br />\n
          It does not include gas insulated substation equipments.<br />\n
          In this standard metalclad switchgear shall be called MC switchgear and station type cubicle<br />\n
          switchgear shall be called SC switchgear. Whenever the data covers both types of equipments,<br />\n
          then they shall be called ME switchgear.

          New IEEE Standard - Superseded.<br />\n
          This standard is a revision of ANSI C37.06-1997. It reflects small editorial changes needed to coordinate with the final wording contained in the defining standards ANSI/IEEE C37.04-1999 and ANSI/IEEE C37.09-1999. Some ratings have also been updated. Because this revision is primarily editorial in nature, this Foreword describes the substantive and editorial changes between this revision and the 1987 version.<br />\n
          The format of the tables remains very much the same, except that some ratings, which had been given in the notes (sometimes on a different page from the table of preferred ratings), have been listed explicitly in the tables.<br />\n
          \t\t\t\t<br />\n
          This standard is applicable to three-pole circuit breakers used in three-phase systems and single-pole circuit breakers used in single-phase systems, both indoor and outdoor AC high-voltage types, rated above 1000 volts on a symmetrical current basis. This standard does not cover circuit breakers used at rated frequencies other than 50 Hz or 60 Hz, or generator circuit breakers that are covered in IEEE Std. C37.013.<br />\n
          Since the existing rating structures are being revised under related projects PC37.04a, PC37.04b, PC37.09a, PC37.09b, PC37.011 and PC37.012, the purpose of this work is to provide relevant values of preferred ratings for the new rating structures. Another purpose is to integrate C37.06, formerly sponsored by NEMA, into the IEEE SA process of standards dvelopment. Sponsorship is now being transferred to the IEEE Switchgear Committee.
