  • 产品名称: CM5X-125 / CM5XL-125 miniature molded case circuit breakers

Overview

CM5X, CM5XL plastic shell circuit breaker (hereinafter referred to as circuit breaker) is a double breakpoint structure technology research and development with the international advanced level of miniaturized circuit breakers, divided into:
——thermal magnetic CM5X-125 circuit breaker, current from 1.5A ~ 125A;
——with residual current protection thermal magnetic CM5XL-125 circuit breaker, current from 1.5A ~ 125A, the residual current from 30mA ~ 500mA.

The circuit breaker is divided into C type (basic type), L type (standard type) and M type (higher breaking type) according to its rated limit short circuit breaking capacity (Icu).
The circuit breaker can be connected to the incoming line.
The circuit breaker can be mounted on a vertical mounting plate or mounted on a horizontal mounting plate and mounted on a rail (CM5X-125).
The circuit breaker has the isolation function, the corresponding symbol is:.
The product meets the following criteria:
IEC 60947-1 and GB 14048.1 General requirements for low - voltage switchgear and control equipment
IEC 60947-2 and GB 14048.2 Low voltage switchgear and controlgear circuit breakers
