The Retrofit Process

Aging switchgear, such as the Brush/Hawker Siddeley VSI R4 circuit breaker, can cause reliability and safety problems in medium voltage work environments, potentially risking harm to both plant and personnel. Fortunately, P&B and GFF Power can provide an economical and unobtrusive solution, without the array of changes usually required for new switchgear installations.

Our Retrofit Switchgear supply partner, P&B, have been manufacturing low-impact designs, including VSI retrofit circuit breakers, to tackle this issue for nearly 30 years. As a result, the Manchester-based company are widely considered a global authority when it comes to retrofitting for modern switchgear requirements.

As with many OEMs of switchgear equipment in Australia, Brush/Hawker Siddeley has its roots in the United Kingdom, where a significant amount of their equipment, including the VSI circuit breaker, has been installed and is now coming to the end of its intended lifespan. Given this, P&B are very familiar with the common retrofit requirements for Brush/Hawker Siddeley circuit breakers and have a wealth of experience with this manufacturer, both at home and abroad.

A refined process

Through years of rigorous research, testing and development, P&B have refined their retrofit processes (from first concepts through to manufacture), utilising modern laser scanning and 3D modelling techniques to maximise the accuracy with which their retrofit models match your existing on-site panel. The result: minimal to no on-site adjustments required.

P&B can offer Brush/Hawker Siddeley Switchgear retrofit designs for the following ratings and models:

Voltage:

3.3kV, 6.6kV, 11kV and 12kV

Current:

400A, 630A, 800A, 1250A and 2000A

Fault rating:

20kA, 25kA, 31.5kA

BIL:

75kV or 95kV

Available Brush/Hawker Siddeley Models:

VSI (R4 & R8 etc.), VMV, VMH

P&B are always striving to improve their retrofit range and capabilities through research and development – please contact us with your requirements to discuss the possibilities for retrofit of your Brush/Hawker Siddeley circuit breakers.
