gascircuit breakers Calibration Safe and efficient

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.

  • Fuse Box Circuit Breaker Safety Tips - Direct Energy

    Circuit breakers came into use because they were safer than fuses. Breakers trip open circuits faster during a circuit fault and can be reset with the flip of a switch. Fuses take time to heat up and blow, and when that happens, you have to purchase and install replacements. You can probably find a fuse box in an older home, but it really should be replaced with a circuit breaker panel for safety’s sake.
