Utilising over 35 years of experience working with heritage Whipp & Bourne assets, we have designed a innovative retrofit solution (RET IFR-NW) for the 415V IFR Whipp & Bourne circuit breaker.

The retrofit consists of installing a Merlin Gerin NW ACB within the existing Whipp & Bourne carriage.

The existing switchboard protection can be retained by using a Non-Automatic type ACB or a new Micrologic Programmable protection relay which can be incorporated with the ACB.

All main interlocks have been retained in the modification to prevent the retrofit being installed or removed from the switchboard whilst in the closed position. By carrying out the retrofit in this way it alleviates the necessity to modify the existing switchboard busbars etc. This method, in our opinion is by far the most cost effective solution for upgrading the switchboard on site. it also guarantees future support and reliability for years to come.

As part of our Whipp & Bourne retrofit package, customer’s drawings are updated on CAD to contemporary standards producing standard drawings for each circuit type.
