Product FAQs

7 answers
What type of mounting does the HLL36015 use?

The HLL36015 is a unit-mount circuit breaker. It uses lugs on both the line and load sides for cable connections and is not designed to plug directly onto an I-Line panelboard bus.

Can I install the HLL36015 in a Square D I-Line panelboard?

No, the HLL36015 is a unit-mount breaker. For an I-Line panelboard, you need the I-Line equivalent, which is catalog number HLA36015.

What are the lug torque requirements for the HLL36015?

For the standard AL150HD lugs, the tightening torque is 44 lbf-in (5 N.m) for 14 to 10 AWG wire, and 124 lbf-in (14 N.m) for 8 to 3/0 AWG wire.

What does the L in the HLL36015 part number indicate?

The L indicates the interrupting rating level. The HLL36015 has a very high interrupting capacity, rated up to 125kA at 240VAC and 100kA at 480VAC, which is significantly higher than standard D, G, or J rated H-Frame breakers.

Is the HLL36015 suitable for reverse-fed applications?

Yes, standard unit-mount PowerPacT H-Frame circuit breakers with factory-sealed thermal-magnetic trip units, like the HLL36015, can be reverse fed.

Is the HLL36015 rated for 100% continuous current?

No, the standard HLL36015 is an 80% rated circuit breaker. For a 100% rated application, you would need the HLL36015C variant.

How can I manually test the tripping mechanism on the HLL36015?

The breaker features an integral push-to-trip button on the front cover, allowing you to manually trip the circuit breaker for testing and maintenance.
