BJA36080 - 80Amp Circuit Breaker

BJA36080 - 80Amp Circuit Breaker

The Schneider Electric BJA36080 PowerPacT™ B circuit breaker provides overcurrent and short-circuit protection for your commercial and industrial electrical distribution systems. Rated at 80 amps with a 3-pole configuration, this thermal-magnetic circuit breaker is commonly used in panelboards, switchboards, HVAC equipment, motor circuits, and feeder applications where reliable circuit protection is required.

Its compact B-frame design helps conserve panel space while providing the interrupting capacity needed for modern electrical systems. The breaker features an I-Line mounting configuration for use in compatible Schneider Electric equipment and includes mechanical load-side lugs for secure field wiring connections.

The BJA36080 uses dual-break rotating contacts that help reduce peak fault current during short-circuit events. This can help you limit stress on downstream equipment and electrical components during fault conditions. A built-in push-to-trip button allows technicians to manually test breaker operation during inspections and maintenance procedures.
