Delivering 70A of thermal-magnetic protection, the Schneider Electric BJA36070 is a 3-pole MCCB. It is part of the PowerPacT B-Frame family, suited for commercial environments. Featuring an I-Line plug-on configuration, it is compatible with Square D panelboards and switchboards. It can also be used to replace discontinued FH36070 components. The breaker provides a 65 kAIC rating at 480VAC with fixed LI trip settings. It comes equipped with a push-to-trip mechanism and load side lugs.
Can the BJA36070 replace older Square D FA series circuit breakers?
Yes. The PowerPacT B-frame is the manufacturer designated replacement for legacy F-frame I-Line breakers, such as the FA36070. It features the same I-Line footprint to allow for easy retrofits in existing panelboards.

What does the "J" signify in the BJA36070 catalog number?
The "J" designates the specific interrupting capacity band of this PowerPacT B-frame breaker. For this model, the J rating provides a 65kA short circuit interrupting rating at 480VAC.
Is this breaker rated for direct current (DC) applications?
