SIM Switchgear has developed an innovative retrofit for obsolete circuit breakers to avoid the potential for failure and power outages.
The Whipp & Bourne MM74 HSCB retrofit process involves installing a GERAPID HSCB housed in the existing chassis.
The new breaker is fitted directly into the existing switchboard without the need for modification. All existing interlocks and winding mechanisms remain the same. Alternatively, we can supply the retrofit as a complete unit.
