本标准涵盖了交流高压断路器的电容电流开关要求，其额定值符合美国国家标准A C高压断路器额定结构C37中给出的方法。04-1964，并在美国国家标准附录中列出了AC高压断路器C37的首选额定值和相关要求能力。06-1972.2预计断路器制造商将努力尽快满足这些新标准的要求。 然而，人们认识到，这将需要时间来完成；提醒用户与制造商协商特定设计是否符合这些标准。本标准发布日期前制造的断路器可能不符合其要求；关于这些早期设计的电容电流切换能力，应咨询制造商。

This standard covers capacitance current switching requirements for ac high-voltage circuit breakers rated in accordance with methods given in American National Standard Rating Structure for A C High-Voltage Circuit Breakers, C37.04-1964, and listed in American National Standard Schedules of Preferred Ratings and Related Required Capabilities for A C High-Voltage Circuit Breakers, C37.06-1972.2 It is anticipated that the manufacturers of circuit breakers will expend efforts to meet the requirements of these new standards as soon as possible. However, it is recognized that this will require time for completion; users are cautioned to confer with the manufacturer as to whether a specific design meets these standards. Circuit breakers manufactured before the publication date of this standard may not meet its requirements; the manufacturer should be consulted concerning the capacitance current switching capabilities of these earlier designs.
