Square D HJA260201 Molded Case Circuit Breaker

Yes, the PowerPacT H-frame series can serve as an alternative solution for legacy Square D F-frame breakers. Specifically, the HJA260201 easily replaces discontinued 2-pole, 20A I-Line breakers like the FH26020, maintaining the same mounting space in your panelboard.

This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It is not compatible with standard unit-mount or load center applications.

The HJA260201 features a plug-on design for the line side, allowing it to snap directly onto the bus of a Square D I-Line panelboard or switchboard. The load side utilizes standard mechanical lugs for your outgoing wire connections.

The standard AL150HD load-side mechanical lugs require specific torque settings based on your wire size. For example, 14 AWG to 10 AWG conductors should be torqued to 44.25 lb-in (5 N.m). Always verify the exact torque specifications printed on the breaker label for larger wire sizes before terminating.

The J designates the interrupting capacity level of the PowerPacT H-frame breaker. For this model, it indicates a high interrupting rating of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.

This specific 2-pole I-Line circuit breaker comes factory-configured for an AB phase connection on the panelboard bus.

The thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads using a fixed thermal element, and Instantaneous (I) protection against short circuits using an adjustable magnetic element.
