Product FAQs
7 answersWhat is the required wire torque for the HLL36050 terminals?
The factory-installed AL150HD lugs accept 14 to 3/0 AWG copper or aluminum wire. The required tightening torque for these terminals is 44.3 lb-in (5 N.m).
What does the L in the HLL36050 part number represent?
The L designates the interrupting capacity tier within the Square D PowerPacT H-frame family. It indicates a high interrupting rating of 100 kA at 480 VAC and 125 kA at 240 VAC.
Which replacement lug kit fits the HLL36050 circuit breaker?
The standard mechanical lug kit for this breaker is part number AL150HD. Each kit contains three lugs and can be used on either the line or load side of the breaker.
Is the HLL36050 rated for 100 percent continuous operation?
No, this breaker is standard-rated for 80 percent continuous current. If your application requires a 100 percent continuous current rating, you will need the HLL36050C variant.
How is the HLL36050 mounted inside an enclosure?
This is a unit-mount circuit breaker, meaning it fastens directly to a backpan or mounting plate using screws. It is not compatible with I-Line panelboards, which require plug-on mounting.
Can I add internal accessories to this PowerPacT H-frame breaker?
Yes, the HLL36050 supports field-installable internal accessories. Auxiliary contacts, alarm switches, shunt trips, and undervoltage releases can be installed behind the front accessory cover.
Is this breaker suitable for use in DC circuits?
Yes, because it utilizes a thermal-magnetic trip unit, it is rated for DC applications. It supports up to 250 VDC or 500 VDC depending on how the poles are wired in series.
