Circuit Breakers

Circuit Breakers are automatic protective devices that allow current to pass under a normal load. In the event of an overload, short circuit, ground fault, or other electrical fault, the circuit breaker acts as a protective device by disconnecting the flow of current.

Success Stories

3P 4000A 600V 200kAIC Eaton Magnum DSX

A customer needed a 3P 4000A 600V 200kAIC Eaton Magnum DSX draw-out circuit breaker to replace a unit that was creating nuisance tripping. We got a call on Saturday AM and delivered the reconditioned/tested breaker nine hours later during the weekend. We have in-house capabilities to repair, recondition, and field modify large circuit breakers up to 6000 amps. We can supply these units for scheduled outages or critical power emergencies after hours on nights and weekends.
