BJA36020 - 20Amp Circuit Breaker

BJA36020 - 20Amp Circuit Breaker

When your reliable circuit protection is needed in a compatible I-Line distribution system, the Schneider Electric BJA36020 is designed to fit the application. This 20A, 3-pole thermal-magnetic circuit breaker is part of the PowerPacT B-frame family and is commonly used in commercial and industrial electrical distribution equipment where a compact I-Line breaker is specified.

The BJA36020 features an ABC phase connection, I-Line line-side termination, and mechanical load-side lugs. Dual-break rotating contacts help you reduce peak current during short-circuit conditions, while the built-in push-to-trip button allows convenient manual testing during maintenance and inspection. Rated for use up to 600Y/347VAC, this breaker offers interrupting capacities up to 100kA at 240VAC and 25kA at 600Y/347VAC.
