Overview

CM5, CM5Z, CM5Z, CM5ZL 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 the new generation of circuit breakers, divided into four series:

——Thermocouple adjustable CM5 series circuit breakers are 63A, 125A, 160A, 250A, 400A, 630A six shell, current from 1.5 A ~ 630A.
——Intelligent CM5Z series circuit breakers are 125A, 160A, 250A, 400A, 630A, 1600A six shell, current from 12.5A ~ 1600A.
——with residual current protection thermo-magnetically adjustable CM5L series circuit breakers are 125A, 250A, 400A, 630A four shell, the current from 1.5 A ~ 630A, the remaining current from 30mA ~ 3A.
——with residual current protection Intelligent CM5ZL series circuit breakers have 125A, 250A, 400A, 630A four shell, current from 12.5A ~ 630A, the remaining current from 30mA ~ 3A.

CM5Z, CM5ZL intelligent circuit breaker optional variety of intelligent release, including the E-type, Z-and iP-type. IP type with a comprehensive power monitoring function, can provide specifications for the 250,400,630 shell.
CM5G series of isolation switch for the CM5 derived products, with standard CM5 Molded Case circuit breaker size, convenient set of factory standardized design.
The circuit breaker is divided into L type (standard type), M type (higher breaking type), type H type (high breaking type), S type (ultra high breaking type) four levels by rated short circuit breaking capacity (Icu) The
Circuit breaker voltage level, the short-circuit breaking capacity level can be inverted line connection.
The circuit breaker can be mounted on a vertical mounting plate or mounted on a horizontal mounting plate.
The circuit breaker has the isolation function, the corresponding symbol is:.
CM5L, CM5ZL circuit breaker can be built-in residual current alarm does not trip module, to avoid significant losses caused by power failure to meet GB13955 Article 4.6 requirements.
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
IEC60947-3 and GB14048.3 Low-voltage switchgear and controlgear Switches, isolators, disconnectors and fuse combinations
IEC60947-4-1 and GB 14048.4 Low-voltage switchgear and control equipment Electromechanical contactors and motor starters (including motor protector)
