Product FAQs
8 answersWhat enclosures and panelboards are compatible with the HGL36060U31X circuit breaker?
This unit-mount H-frame breaker is compatible with PowerPacT H-Frame enclosures, industrial control panels, and switchboards. It can also be utilized as a main breaker in Square D NF and NQ panelboards.
What type of trip unit is included with the HGL36060U31X?
The U31X suffix indicates this breaker is equipped with a Micrologic 3.2 electronic trip unit. This solid-state trip unit provides adjustable Long-Time (L) and Instantaneous (I) protection settings for precise coordination.
What are the standard lugs provided on this H-frame breaker?
The HGL36060U31X comes standard with AL150HD mechanical lugs on both the line and load sides. These lugs accept 14 to 3/0 AWG aluminum or copper wire.
What does the G in the HGL36060U31X part number signify?
The G designates the interrupting capacity tier within the PowerPacT H-Frame series. It provides a short-circuit current rating of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Can I use the HGL36060U31X to replace an older thermal-magnetic H-frame breaker?
Yes, this breaker shares the same physical footprint and mounting dimensions as other unit-mount PowerPacT H-frame breakers. However, you must verify that the Micrologic 3.2 electronic trip unit and its LI protection profile meet your specific engineering requirements.
What is the recommended torque for the AL150HD lugs on this 60A breaker?
The standard AL150HD mechanical lugs require specific torque depending on the wire size used. For 14 to 10 AWG wire, the specified torque is 44.3 lb-in (5 N.m). Always verify the exact torque requirements printed on the breaker faceplate or lug before terminating larger conductors.
Does the HGL36060U31X provide ground fault protection?
No. The Micrologic 3.2 trip unit only provides Long-Time (L) and Instantaneous (I) protection. It does not include Ground Fault (G) or Short-Time (S) protection functions.
Can this 3-pole breaker be used in a single-phase application?
Yes, Square D PowerPacT H-frame breakers with standard Micrologic trip units are marked for single-phase use on 240VAC circuits. You can use any two poles for the connection.
