Product Description

1.Application

BKN miniature circuit breaker is applicable to a line of AC 50Hz/60Hz, 230V in singlepole, 400V in double, three,
four poles for protecting overload and short circuit, and rated cur-rent up to 63A.

It can also be used for infrequent line conversion under the normal condition.

Thebreaker is applicable to lighting distribution system in industrial enterprise, commercially district,high-rise building and
dwelling house.

It conforms with the standards of IEC60898.
