Product FAQs
7 answersWhat type of trip unit is installed in the HRL36100U31X?
This breaker features the Micrologic 3.2 electronic trip unit. It provides adjustable dials for both long-time pickup and instantaneous (LI) trip settings to coordinate with your specific system requirements.
How is the HRL36100U31X mounted in a panel?
It is a unit-mount circuit breaker designed for feed-thru applications. It secures via mounting hardware and features line and load lugs rather than I-Line plug-on jaws.
Can I use the HRL36100U31X in a Square D I-Line panelboard?
No. The HRL36100U31X is a unit-mount breaker with lugs on both ends. For an I-Line panelboard, you must use an I-Line plug-on variant.
Do I need to purchase separate lugs for the HRL36100U31X?
No. This unit-mount breaker comes with factory-installed line and load lugs that accept 14 AWG to 3/0 AWG aluminum or copper wire.
What does the R in the HRL36100U31X part number indicate?
The R designates the interrupting rating class. In the PowerPacT H-frame series, R-class breakers provide an ultra-high current-limiting interrupting rating of 200kA at 480VAC and 100kA at 600VAC.
Does this breaker provide ground fault protection?
No. The Micrologic 3.2 trip unit provides long-time and instantaneous (LI) protection only. It does not include ground fault or short-time protection.
