Circuit Breaker

Circuit breakers interrupt a circuit the moment current climbs past what the conductor can carry, then reset and go back into service instead of being thrown away like a blown fuse. Plant electricians change them out when a breaker trips repeatedly and will not hold, when a discontinued frame has to be matched to a panel that is still in service, or when a new circuit needs protection sized to its load.

 

As an authorized electrical distributor for multiple manufacturers, we stock bolt-on and plug-in, hydraulic, magnetic, miniature and molded case breakers across competing lines, so you can match the frame the panelboard was built for, compare trip characteristics across brands, and pick the type the application calls for.
