Product FAQs

5 answers
What specific trip unit is included with the HDA36100U44X?

This breaker features a Micrologic 6.2A electronic trip unit. In addition to providing LSIG (Long-Time, Short-Time, Instantaneous, and Ground-Fault) protection, the 6.2A trip unit includes an integrated ammeter for current monitoring.

What is the standard lug kit provided with the HDA36100U44X?

It comes standard with the AL150HD lug kit, which accepts aluminum or copper wiring from 14 AWG to 3/0 AWG.

How is the HDA36100U44X configured for phase connection in I-Line panels?

As a standard 3-pole I-Line breaker, it is factory-configured for an ABC phase connection. The plug-on design allows it to securely connect to the busbar system in Square D I-Line panelboards and switchboards.

Can the HDA36100U44X be reverse-fed?

Yes, this breaker is suitable for reverse connection. However, because it uses a Micrologic A (Ammeter) trip unit, you must verify and properly configure the reverse power flow settings to prevent unexpected tripping during backfeed applications.

Is the HDA36100U44X 100% rated for continuous duty?

No, this breaker is standard-rated (80%) for continuous current. PowerPacT H-Frame breakers in the I-Line plug-on configuration are not available with a 100% continuous current rating.
