BJA36100 - 100Amp Circuit Breaker

BJA36100 - 100Amp Circuit Breaker

The Schneider Electric BJA36100 PowerPacT™ B circuit breaker is a 100 amp, 3-pole thermal-magnetic breaker for your commercial and industrial power distribution systems. It is frequently found in panelboards, switchboards, HVAC equipment, motor circuits, and feeder applications where overcurrent protection is required.

Dual-break rotating contacts help you reduce peak fault current during short-circuit events, which may help reduce stress on connected equipment. The breaker also includes a built-in push-to-trip button, allowing technicians to manually trip and test the breaker during inspections and maintenance.
