Product FAQs
6 answersWhat panelboards are compatible with the PJA36100?
The PJA36100 is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection on the line side and mechanical lugs on the load side.
Can the PJA36100 replace older Square D 1000A I-Line breakers?
Yes, the PowerPacT P-frame PJA36100 serves as a drop-in replacement for discontinued Square D M-frame breakers, including the MA36100 and MH36100. It shares the same dimensions, mounting, bussing, and door cut-out as the legacy M-frame models.
Does the PJA36100 require a separate mounting bracket for I-Line panels?
No additional mounting bracket is required. The I-Line plug-on connectors and mounting bracket are integral to the circuit breaker and allow for direct installation onto the panelboard bus.
What type of trip unit is installed in the PJA36100?
This breaker features a solid-state ET 1.0I electronic trip unit with LI (Long-Time and Instantaneous) protection functions. The long-time protection is fixed, while the instantaneous trip is adjustable to coordinate with your system's fault current requirements.
Can I use aluminum wire with the PJA36100 load lugs?
Yes, the factory-installed mechanical load lugs are dual-rated for both aluminum and copper wire. They accept four 3/0 AWG to 500 kcmil conductors per phase.
How do I manually test the mechanical operation of the PJA36100?
Like all PowerPacT circuit breakers, the PJA36100 features an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the mechanical operation of the trip mechanism before or after installation.
