Compact substation RMU lateral VS1 vacuum switch ZN63A(VS1) 12 indoor

Product Overview

Description

Compact substation RMU lateral VS1 vacuum switch  ZN63A(VS1)-12  indoor

ZN63A(VS1)-12 Side mounting vacuum circuit breaker is a type of high voltage switch

equipment which appropriate to 12kv, 50Hz three phase alternating current system, applicable for protecting and controlling, especially appropriate to frequent operation and short circuit places. This type is mainly used in fixed type switchgear, it can not only use alone, but also in loop network, box-type and other kinds of nonstandard power supply system.
