AH 3.3KV AIR CIRCUIT BREAKER RETROFIT

The new SIM Switchgear retrofit for the Whipp & Bourne 3.3KV AH Air Circuit Breaker provides a quick and efficient upgrade for obsolete systems.

The retrofit involves installing an ABB VD4 Circuit Breaker within the existing Whipp & Bourne Carriage. The main earthing and interlocking are modified to work with the VD4 Circuit Breaker.

This method enables a rapid switchgear upgrade without the need to modify existing switchboard busbars. An inexpensive way to guarantee support for many years to come.

Additionally, SIM Switchgear will update any technical drawings on CAD to comply with the latest standards for each circuit type.

Advantages:

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