Regarding after-sales service:
Regarding logistics:
The CM3, CM3E, CM3L, and CM3DC plastic shell circuit breakers (hereinafter referred to as circuit breakers) of Changshu Switch Factory are the upgraded CM1 series products launched by our company, divided into four major series:
The thermal magnetic CM3 series circuit breaker has six frames, including 63A, 100A.250A, 400A, 630A, and 800A, with currents ranging from 10A to 800A.
The electronic CM3E series circuit breaker has six housing frames, including 100A, 250A, 400A. 630A, 800A, and 1250A, with currents ranging from 12.5A to 1250A
The CM3L series circuit breaker with residual current protection has four frames: 100A, 250A, 400A, and 630A, with currents ranging from 10A to 630A and residual currents ranging from 30mA to 30A.
The DC CM3DC series circuit breaker has five frames, including 100A, 250A, 400A, 630A, and 800A, with currents ranging from 10A to 800A.
Circuit breakers are classified into four levels based on their rated ultimate short-circuit breaking capacity (Iu): C-type (basic type), L-type (standard type), M-type (higher breaking type), and H-type (high breaking type).
The CM3 circuit breaker has a breaking capacity level of C, L, M type, and the CM3E circuit breaker has a breaking capacity level of M type. When used in AC400V distribution systems, it can be connected to the incoming line.
The entire series of circuit breakers can be installed horizontally (horizontally), vertically (vertically), or horizontally.
