Product FAQs

8 answers
What specific trip unit model is installed in the PGL36040U33A?

This breaker comes equipped with a Micrologic 5.0 electronic trip unit. In addition to adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection, it features true RMS sensing and Zone Selective Interlocking (ZSI) for advanced system coordination.

Can I swap the trip unit on the PGL36040U33A if my protection requirements change?

Yes, PowerPacT P-frame breakers feature interchangeable Micrologic trip units. You can upgrade or replace the trip unit in the field without needing to replace the entire breaker frame.

Is the PGL36040U33A rated for 100 percent continuous current?

No, this breaker is standard-rated to carry 80 percent of its continuous current rating.

Can I mount the PGL36040U33A directly to a backpan or enclosure?
