Square D JLA36200 Molded Case Circuit Breaker

This breaker features an I-Line plug-on connection for the line side, allowing it to snap directly onto the bus of a Square D I-Line panelboard or switchboard. Mechanical lugs are used for wire termination on the load side.

No. The JLA36200 is exclusively designed for Square D I-Line panelboards and switchboards. It will not fit in QO, NQ, NF, or standard applications that require unit-mount hardware.

While both are 200-amp, high-interrupting breakers in the PowerPacT J-Frame family, their mounting styles differ. The JLA36200 has an I-Line plug-on connection on the line side and lugs on the load side. The JLL36200 is a unit-mount breaker that uses mechanical lugs on both the line and load sides.

The "L" indicates the breaker's short-circuit interrupting rating. In the PowerPacT J-Frame family, the L-rating designates a high-interrupting capacity, delivering up to 100kAIC at 480VAC and 125kAIC at 240VAC.

Yes. The load side of the breaker comes factory-equipped with mechanical lugs (typically catalog number AL250JD) that are dual-rated for aluminum and copper conductors. The line side utilizes the I-Line plug-on jaws, so line-side lugs are not required.

No. This breaker is standard-rated at 80%. According to NEC guidelines, continuous loads (those operating for 3 hours or more) should not exceed 80% of the breaker's 200-amp maximum capacity, which equates to 160 amps.

Yes. A push-to-trip button is located on the front of the breaker. This allows electricians to manually trip the device to verify the mechanical linkage is operating correctly and to test any connected auxiliary accessories.

The thermal (overload) trip on this breaker is fixed at 200 amps, but it features an adjustable magnetic (short-circuit) trip setting. This allows you to fine-tune the instantaneous trip response based on the specific fault current requirements of your application.
