Project Description

C45N Miniature Circuit Breaker

C45N Miniature Circuit Breaker (MCB) is applicable to a line of AC 50Hz/60Hz, 230V in single pole, 400V in double, three,four poles for protecting overload and short circuit, and rated current up to 63A. It also bused for in frequent line conversion under the normal condition. The breaker is applicable to lighting distribution system in industrial enterprise, commercially district, high-rise building and dwelling house. It conforms to the standards of IEC60898.
