Product Description

VB12-63 series MCB, used as overload and short circuit protection, applies to a circuit of AC  50Hz,rated voltage 230/400V, rated current up to 63A. Usually it functions as un frequently switching. In addition, it can be also used as an isolator to cut off the circuit for maintenance of circuit and equipment.


Application

Industry and commercial buildings, high-rise buildings and residential houses, etc.

Conforms to standard: IEC/EN 60898-1
