bH 6.6KV AIR CIRCUIT BREAKER RETROFIT

Old and obsolete circuit breakers are prone to failure. SIM Switchgear provide a retrofitting service to prevent costly problems such as power outages.

The vacuum retrofit for the Whipp & Bourne 6.6KV BH Air Circuit Breaker involves installing a new ABB VD4 Circuit Breaker into the existing carriage.

Slight modifications are undertaken to the main earthing and interlocking, but switchboard busbars remain untouched. It’s a cost-effective way to ensure uninterrupted power and future support.

The retrofit package includes updating standard drawings for each circuit type on CAD.

Advantages:

– Efficient Upgrade For Aging Equipment
– Guaranteed Future Support
– Innovative Method Saves Time & Money
– Updated CAD Drawings
