Product Description

HKC65 Series Miniature Circuit Breaker

1. Application

HKC65 are 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 can also beused for infrequent line conversion under the normal condition. The breaker is applicable tolighting distribution system in industrial enterprise, commercially district, high-rise building anddwelling house. It conforms with the standards of IEC60898.
