Product FAQs
5 answersWhat legacy Square D circuit breakers does the PJA36080CU41A replace?
This PowerPacT P-frame breaker serves as a direct replacement for legacy Square D MA36080 and MH36080 800A I-Line circuit breakers.
What does the "C" in the PJA36080CU41A catalog number indicate?
The "C" indicates that this circuit breaker has a 100 percent continuous current rating. This allows the breaker to carry its full 800A capacity continuously without the standard 80 percent derating requirement.
What specific features does the Micrologic 3.0A trip unit provide on this breaker?
The factory-installed Micrologic 3.0A electronic trip unit provides adjustable long-time and instantaneous protection. The "A" designation indicates it includes an integrated ammeter for accurate current monitoring and fault response.
Can the Micrologic trip unit on this P-frame breaker be swapped in the field?
Yes, PowerPacT P-frame breakers equipped with Micrologic trip units allow the trip unit to be interchanged in the field. This provides flexibility to upgrade protection functions without replacing the entire breaker frame.
How can I manually test the mechanical operation of this breaker?
The breaker includes an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the mechanical operation of the tripping mechanism.
