ZN63A(VBM7)-12 12KV 24KV Side-mounted high voltage vacuum circuit breaker-Liebang Electric Technology Equipment Manufacture

ZN63(VBM7)-12 Side-mounted indoor high-voltage vacuum circuit breaker

Product overview

ZN63-12(VBM7) Side-mounted vacuum circuit breaker is suitable for use in three-phase power systems with a rated voltage of 12kV and a frequency of 50Hz. It is used as a protection and control appliance. It is especially suitable for frequent operations that require rated current, or for breaking short-circuit current multiple times place.

ZN63-12(VBM7) series indoor mounted high-voltage AC vacuum circuit breaker adopts fixed installation and is mainly used in fixed switch cabinets. The circuit breaker can be used alone or in ring network power supply, box-type substation or various non-standard power supply systems.
