Bolt On Circuit Breaker

Bolt-on circuit breakers fasten to the panel bus with screws instead of clipping onto a stab, giving a connection that will not shake loose under vibration or work its way out under a heavy sustained load. Panel builders bolt them in when a plug-in breaker has loosened and started arcing at the stab, when a panelboard schedule calls for a bolted connection on a critical feeder, or when new gear has to survive in a high-vibration bay.

 

As an authorized electrical distributor for multiple manufacturers, we stock them across competing lines in one, two, three and four-pole configurations, across FD, JD and WL frames, so you can match the frame the panelboard was built for, compare amperage and pole count brand to brand, and size the current rating to the feeder it protects.
