Description
Providing reliable power distribution, the LC36500 3-pole, 500A MCCB belongs to Square D's legacy L-Frame series. It delivers robust thermal-magnetic protection with long-time and instantaneous (LI) trip functions. This breaker mounts into Square D I-Line panelboards and switchboards. For modern upgrades, the PowerPacT LJA36600U31X serves as a substitute when adjusted to 500A. Rated at 65kAIC at 480V, this extra-high interrupting capacity breaker is HACR rated and includes load-side lugs.Specifications

Product FAQs
6 answersCan I install the LC36500 in a standard QO or NQ panelboard?
No. This breaker features an I-Line plug-on line side connection and is exclusively compatible with Square D I-Line panelboards and switchboards. It will not fit in QO, NQ, or NF series load centers.
Does this breaker require bolt-on connections for the line side?
No. The line side uses an I-Line plug-on mechanism that mounts directly onto the panelboard bus, eliminating the need for bolt-on line connections. The load side, however, requires standard wire connections at the mechanical lugs.
Do the load side lugs on the LC36500 accept both aluminum and copper wiring?
Yes, the factory mechanical lugs are dual-rated for both aluminum and copper conductors. They are designed to accommodate two separate cables per phase, ranging in size from 4/0 AWG up to 500 kcmil.
How do I adjust the trip settings on the LC36500?
This breaker uses a thermal-magnetic trip unit. The thermal element for long-time overload protection is fixed and cannot be changed. However, the magnetic element for instantaneous short-circuit protection features an adjustable dial to fine-tune the trip threshold.
What does the Extra High Interrupting designation mean for this breaker?
It indicates the breaker is engineered to safely clear severe electrical faults in high-capacity environments. This is reflected in its high interrupting ratings, such as 100kA at 240V AC and 65kA at 480V AC.
Is the LC36500 considered a legacy circuit breaker?
Yes, the LC36500 is part of the legacy Square D L-Frame series. While it remains heavily used and supported in existing industrial infrastructure, newer panelboard installations typically utilize the modernized PowerPact L-Frame series.
