Scope

This standard specifies the classification, product data and information, normal working conditions and installation conditions, requirements, inspection rules and test methods for thermal-magnetic molded case circuit breakers. This standard applies to thermal-magnetic molded case circuit breakers (hereinafter referred to as circuit breakers) used in circuits with an AC frequency of 50 Hz/60 Hz, a rated working voltage of 690 V or lower, or a DC voltage of 250 V or lower. Circuit breakers are generally used in power distribution networks for power distribution, to distribute electrical energy and serve as overload, short-circuit, and undervoltage protection for lines and power supply equipment. Three-pole and four-pole circuit breakers can also be used for motor protection, serving as overload, short-circuit, and undervoltage protection for motors. Circuit breakers should have an isolation function. This standard does not include circuit breakers specifically designed for photovoltaic power generation. This standard specifies the classification, product data and information, normal working conditions and installation conditions, requirements, inspection rules and test methods for thermal-magnetic molded case circuit breakers.
