Product FAQs
6 answersWhat enclosures or panels is the HLL36040 compatible with?
As a unit-mount circuit breaker, it is designed for control panels, switchboards, and industrial enclosures. It is not compatible with Square D I-Line panelboards, which require a plug-on I-Line bracket.
Can the HLL36040 be reverse fed?
Yes. Standard unit-mount PowerPacT H-frame thermal magnetic circuit breakers have factory sealed trip units and are suitable for reverse-feed applications.
What are the lug torque specifications for this breaker?
The standard AL150HD lugs require 44.3 lb-in (5 N.m) of torque for 14 to 10 AWG wire, and 123.9 lb-in (14 N.m) for 8 to 3/0 AWG wire.
What do the letters in the HLL36040 catalog number indicate?
The 'H' denotes the PowerPacT H-frame. The first 'L' indicates the interrupting rating (100kA at 480VAC). The second 'L' specifies it is a unit-mount breaker with lugs on both the line and load sides.
Is this circuit breaker HACR rated?
Yes, the HLL36040 carries an HACR rating, making it suitable for heating, air conditioning, and refrigeration motor group applications.
What is the continuous current rating for this breaker?
It is a standard 80% rated circuit breaker, meaning the continuous load should not exceed 32 amps (80% of its 40A rating).
