Product FAQs
5 answersCan the HLL36045 be installed in a Square D I-Line panelboard?
No, this is a unit-mount circuit breaker designed for control panels, switchboards, and industrial enclosures. It features lugs on both the line and load sides and lacks the plug-on jaw connections required for I-Line panelboards.
Is the HLL36045 circuit breaker suitable for reverse feeding?
Yes, standard thermal-magnetic PowerPacT H-frame circuit breakers are suitable for reverse feeding applications.
What is the recommended tightening torque for the factory-installed lugs?
The standard AL150HD mechanical lugs require a tightening torque of 44.3 lb-in (5 N.m) for 14 AWG to 10 AWG conductors, and 123.9 lb-in (14 N.m) for 8 AWG to 3/0 AWG conductors.
Are internal accessories like shunt trips field-installable on this breaker?
Yes, the PowerPacT H-frame design allows for field-installable internal accessories, including shunt trips, undervoltage releases, auxiliary switches, and alarm switches. These install directly behind the front cover.
What do the letters in the HLL36045 catalog number signify?
The first H designates the PowerPacT H-frame. The first L indicates the interrupting rating tier, which provides 100kAIC at 480VAC. The second L specifies a unit-mount configuration with mechanical lugs on both the line and load sides.
