Product FAQs
6 answersWhat type of panelboard is required for the LE36225LI circuit breaker?
This breaker requires a Square D I-Line panelboard or switchboard. It utilizes an I-Line style plug-in connection, which is not compatible with standard bolt-on or load center applications.
Is the LE36225LI still in active production?
No, the LE frame is a legacy molded case circuit breaker. It has been superseded by the Square D PowerPacT L-Frame series. If you are replacing an existing unit, a PowerPacT L-Frame with an I-Line connection and Micrologic trip unit is the modern equivalent.
What protection functions are included in the LE36225LI electronic trip unit?
The LI designation in the catalog number signifies adjustable Long-Time and Instantaneous trip functions. This solid-state Micrologic trip unit offers more precise overcurrent and short-circuit protection compared to standard thermal-magnetic breakers.
How is the LE36225LI secured inside the electrical panel?
It uses an I-Line style plug-in connection, where the breaker jaw contacts push directly onto the panelboard busbar stack. The load side utilizes standard mechanical lugs for wire termination.
What safety and testing standards does the LE36225LI meet?
This breaker is UL 489 listed and CSA certified for commercial and industrial applications. Additionally, it is HACR rated for use with heating, air conditioning, and refrigeration equipment.
Does the LE36225LI require a rating plug to operate?
Yes, as a Micrologic electronic trip breaker, it requires a compatible rating plug to establish the maximum continuous current rating for the circuit.
