Product FAQs
7 answersCan I install the HLL36020 in a Square D I-Line panelboard?
No. The HLL36020 is a unit-mount circuit breaker with feed-thru lugs on both ends, designed for control panels, switchboards, and enclosures. For I-Line panelboards, you need an I-Line style plug-in breaker.
What does the "L" in the HLL36020 catalog number signify?
The second letter "L" indicates the interrupting rating tier. In the PowerPacT H-frame series, the "L" rating provides a high interrupting capacity of 125kA at 240VAC and 100kA at 480VAC.
What does the "LI" trip function code mean on this breaker?
"LI" stands for Long-Time and Instantaneous trip functions. The Long-Time function provides thermal overload protection, while the Instantaneous function provides magnetic short-circuit protection.
Is the HLL36020 suitable for reverse-feed applications?
Yes. PowerPacT H-frame thermal-magnetic circuit breakers are suitable for reverse connection, allowing them to be reverse-fed in your application.
What is the difference between the HLL36020 and the HDL36020?
The difference is the interrupting capacity. The HLL36020 features an "L" rating (125kA at 240VAC, 100kA at 480VAC), while the HDL36020 has a standard "D" rating (25kA at 240VAC, 18kA at 480VAC). Both share the same 20A, 3-pole, unit-mount physical footprint.
What is the standard lug kit included with the HLL36020?
This breaker comes standard with AL150HD mechanical lugs on both the line and load sides, which accept 14 AWG to 3/0 AWG aluminum or copper wire.
Does this breaker include a push-to-trip feature?
Yes, PowerPacT H-frame circuit breakers feature an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify the mechanical linkage is functioning properly.
