Built for industrial applications, the Square D HJL36060 is a 3-pole, 60A MCCB. It provides thermal-magnetic (LI) trip functions within the PowerPacT H-Frame architecture. Serving as a drop-in substitute for the FCL36060, this unit-mount breaker installs into switchboards and motor control centers. It includes lugs for 14-3/0 AWG wire. Delivering 65kAIC at 480VAC, this current-limiting device is HACR rated and features a Visi-Trip indicator. It is mercury-free and PVC-free.
What does the "J" in the HJL36060 catalog number mean?
The "J" identifies the interrupting rating tier of the PowerPacT H-frame. This provides a maximum interrupting capacity of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
What is the difference between the HJL36060 and HJA36060?
The HJL36060 is a unit-mount circuit breaker with lugs on both the line and load sides. The HJA36060 features an I-Line plug-on connection on the line side specifically for Square D I-Line panelboards.
What enclosures or panels are compatible with the HJL36060?
As a feed-thru, unit-mount breaker, it is designed to be bolted directly to a backpan or mounting plate in industrial control panels, switchboards, and motor control centers rather than plugging onto a pre-built bus.
Can I use aluminum wire with the factory lugs?
Yes. The standard factory-installed lugs accept 14 AWG to 3/0 AWG for both aluminum and copper conductors.
What are the magnetic trip current thresholds for this 60A breaker?
The thermal-magnetic trip unit features a fixed magnetic hold current of 800A and a fixed magnetic tripping current of 1450A.
Can the HJL36060 be reverse fed?
Yes. PowerPacT H-frame unit-mount breakers equipped with standard thermal-magnetic trip units are suitable for reverse connection, meaning line power can be supplied to either the top or bottom terminals.
Does this breaker support 100 percent continuous current?
No. The standard HJL36060 is rated for continuous loads up to 80 percent of its maximum 60A capacity.
