The team at R&B Switchgear Group recently conducted the final inspection and testing of 3 x heritage Whipp & Bourne DV40 Circuit Breakers, ready for them to be returned to the energy client and reinstated back into their power network. 👏

Originally manufactured in 1990, these circuit breakers had reached what should have been the end of their life-cycle after being in service for over 30 years.

However, following a complete overhaul by our specialist engineers, which involved stripping down the equipment and rebuilding it to as-good-as-new condition, with new vacuum bottles from Vacuum Interrupters, the circuit breakers are now ready for another 30+ years of service!

R&B Switchgear Group specializes in the design, build, installation, and commissioning of bespoke LV & MV Switchgear. It also offers worldwide services such as switchgear and circuit breaker maintenance, repairs, retrofitting, upgrades, and modifications. R&B’s focus is to provide turn-key solutions that guarantee optimal performance and maximum lifespan of electrical infrastructure.
