Product Description

General

WSB7-63 series high breaking miniature circuit breaker is applied in line of AC 50/60Hz, rated voltage 230/400V and rated current upto 63A for overload and short circuit protection, also for usage of infrequent operation switching of line under nomal circumstance. It is used at places of industrial, commercial, high-rise and residula buildings, meets standards IEC/EN60898-1 and GB10963.1.

WSB7LE-63 series redisual current operation circuit breaker (with over-current protection) is applied in line of AC 50/60Hz, rated voltage 240/400V and rated current upto 63A. The residual current operation circuit breaker can cut fault current in a very short time period when personal touching or current leakage of the net exceeding the specified value. It can also for usage of overload, short circuit, infrequent switching of the line, and infrequent starting of the motor. The product is used at place of industrial, commercial, high-rise and residential building, meets standards of IEC 61009-1 and GB 16971.1
