Product FAQs
6 answersWhat trip unit is installed on the PJP36100U31A?
This breaker features the MicroLogic 3.0 electronic trip unit. The U31A suffix indicates it provides adjustable long-time and instantaneous (LI) trip functions.
What does Unit Mount mean for this P-frame breaker?
Unit mount indicates the breaker bolts directly to the backpan or bus structure using traditional feed-thru connections. This is different from I-Line breakers, which plug directly onto a specialized panelboard bus.
Is the PJP36100U31A rated for 100 percent continuous current?
No, this is a standard 80 percent rated circuit breaker. Applications requiring a 100 percent continuous current rating need a catalog number containing a C after the amperage, such as PJP36100CU31A.
Does this breaker provide ground fault protection?
No, the included MicroLogic 3.0 trip unit only provides long-time and instantaneous (LI) protection. It does not include equipment ground fault (LSIG) capabilities.
What is the difference between PJP and PJA circuit breakers?
PJP breakers are unit mount devices designed to bolt onto a backpan or bus. PJA breakers share the same electrical ratings but feature an I-Line plug-on connection for Square D I-Line panelboards.
Can I add a shunt trip or undervoltage release to this breaker?
Yes, PowerPacT P-frame circuit breakers accept a variety of field-installable accessories, including shunt trips, undervoltage releases, and auxiliary switches, which mount internally under the front cover.
