Product FAQs
6 answersWhat types of enclosures and panels is the HJM36100 compatible with?
This unit mount circuit breaker is designed for use in Square D enclosures, switchboards, and motor control centers. It features a feed-thru connection and does not plug onto I-Line busbars.
What does the J in the HJM36100 catalog number indicate?
The J denotes the interrupting rating tier for this PowerPacT H-frame breaker. It signifies a high interrupting capacity of 100kA at 240V AC and 65kA at 480V AC.
How does the trip unit function on the HJM36100?
It utilizes a thermal magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal element provides delayed overload protection, while the magnetic element responds immediately to short circuits.
Can the HJM36100 be used in DC applications?
Yes, this breaker is rated for DC systems up to 250V DC, providing an interrupting capacity of 20kA at that voltage.
What is the difference between unit mount and I-Line mounting for this breaker?
The HJM36100 is a unit mount breaker, meaning it bolts directly to a backpan or enclosure and uses lugs for wire connections on both the line and load sides. I-Line breakers plug directly into a specialized busbar on the line side.
What safety procedures are required when installing this feed-thru breaker?
Always de-energize the switchboard or motor control center before installation. Verify that the system voltage and available fault current do not exceed the breaker maximum ratings of 600V AC and 100kAIC. Ensure all lug connections are properly torqued.
