Product Introduction

General

VCB unit, as known as V-unit has vacuum bubble, uses for breaking short-circuit current, one double-position disconnecting switch

is connected in series with the circuit breaker.

When the disconnecting switch at open position, the interlocked earthing switch can be closed to ground the cable cassing.

The operation between the VCB and the disconnecting switch, and the operation between the disconnecting switch and the

earthing switch are mechanically interlocked.
