Product FAQs
6 answersWhat type of panelboard is required for the PGA36100U41A?
This breaker features an I-Line plug-in connection and is designed exclusively for use in Square D I-Line panelboards and switchboards that can accommodate PowerPacT P-Frame breakers.
What does the U41A suffix in the PGA36100U41A catalog number indicate?
The U41A designates that the breaker is equipped with a Micrologic 3.0A electronic trip unit. This provides adjustable Long-Time and Instantaneous (LI) trip functions, along with an integrated ammeter for current monitoring.
Can the PGA36100U41A be used to replace older Square D breakers?
Yes, this PowerPacT P-Frame breaker serves as a modern replacement for legacy Square D MA-frame breakers, such as the MA361000, in existing I-Line panelboards.
What is the wire capacity for the lugs on this 1000A breaker?
The factory-installed lugs on the PGA36100U41A accept four 3/0 AWG to 500 kcmil aluminum or copper cables per phase.
Does the PGA36100U41A include ground fault protection?
No, the included Micrologic 3.0A trip unit provides only Long-Time and Instantaneous (LI) protection. If your application requires ground fault protection, you will need a breaker with a Micrologic 6.0A (LSIG) trip unit, such as the PGA36100U44A.
Does this breaker require a separate mounting kit for I-Line panels?
No, the PGA36100U41A comes with the I-Line bracket and plug-in jaw assembly factory-installed, allowing it to mount directly onto the panelboard bus without additional hardware.
