Scope

Scope: This document specifies the test conditions, test methods, determination criteria, and grade classification of the lifespan of low-voltage circuit breakers. This document applies to low-voltage circuit breakers (hereinafter referred to as "circuit breakers") whose main contacts are used to connect to circuits with a rated voltage of no more than 1,000 V AC or 1,500 V DC. Circuit breakers with a rated voltage higher than 1,000 V AC but not exceeding 1,500 V AC can be implemented as a reference.
