Square D HGL36060 Molded Case Circuit Breaker

The standard AL150HD line and load lugs require different torque settings based on the wire size. For 14 to 10 AWG wire, tighten to 44 lb-in (5 N.m). For 8 to 3/0 AWG wire, tighten to 124 lb-in (14 N.m).

No. The HGL36060 is a unit-mount circuit breaker that connects using wire and lugs on both ends. For a direct plug-on connection to an I-Line distribution bus, you must source the I-Line equivalent, catalog number HGA36060.

The "G" designates the specific interrupting capacity tier within the Square D PowerPacT H-frame family. It indicates the breaker is rated to safely clear fault currents up to 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.

The Long-Time thermal function provides overload protection by tripping when a sustained overcurrent is detected. The Instantaneous magnetic function provides short-circuit protection, tripping immediately during massive fault currents. For the 60A HGL36060, the factory-fixed instantaneous hold current is 800A, and the trip current is 1450A.

When landing conductors in the standard AL150HD terminal lugs, you should strip the wire exactly 0.63 inches (16 mm) to ensure proper seating and electrical contact.

This breaker features dedicated internal slots under the front cover. It can accommodate up to two auxiliary switches (OF), one alarm switch (SD), one overcurrent trip switch (SDE), and one voltage release such as a shunt trip (MX) or undervoltage release (MN).

All Square D PowerPacT circuit breakers are equipped with an integral push-to-trip button located on the front face. Pressing this button manually tests the tripping mechanism and leaves the breaker in the tripped position, allowing you to safely verify proper mechanical operation.

Yes, this thermal-magnetic PowerPacT H-frame breaker is suitable for reverse-feed installations. Because it does not have directional line and load restrictions, power can be supplied to either set of terminal lugs.
