Description
Built for robust industrial applications, the Square D LXL36250E2100 provides reliable circuit protection in a 3-pole, 250A electronic trip MCCB format. This unit-mount breaker is designed for legacy Square D L-Frame enclosures and switchboards. It includes line and load lugs and is replaced by the PowerPacT L-Frame (LJL36250U31X). With a 65kAIC rating at 480V, it features configurable LSI trip functions. A factory-installed alarm switch provides immediate status indication.Specifications

Product FAQs
7 answersWhat type of enclosures or panels accept this circuit breaker?
This unit-mount breaker is designed for installation in legacy Square D L-Frame enclosures and switchboards.
What do the LSI functions on the Micrologic trip unit allow you to adjust?
LSI stands for Long-Time, Short-Time, and Instantaneous trip functions. These adjustable settings allow electricians and panel builders to fine-tune the breaker's response curve for precise selective coordination in complex distribution systems.
What wire sizes are compatible with the line and load lugs?
The included lugs accept either a single 1 AWG to 600 kcmil conductor or two 1 AWG to 250 kcmil conductors per phase. They are rated for both aluminum and copper (Al/Cu) wiring.
Is the LXL series still actively manufactured by Square D?
No, the LXL series is a legacy molded case circuit breaker. For modern upgrades, Square D has replaced this line with the PowerPact L-Frame series, such as the LJL36250U31X, though specific retrofit requirements may apply.
Can this breaker be installed in a Square D I-Line panelboard?
No, this specific model is a unit-mount breaker designed for standalone enclosures or switchboard mounting. It lacks the plug-on jaw connections required for I-Line panelboards.
Can the trip unit on this breaker be swapped out for a different rating?
No, this breaker is equipped with a Micrologic Series B non-interchangeable solid-state trip unit. The trip unit cannot be removed or swapped in the field.
What is the advantage of the electronic trip unit over a standard thermal-magnetic breaker?
The solid-state electronic trip unit provides higher accuracy, better repeatability, and adjustable LSI parameters. This ensures superior overcurrent protection and allows for tighter coordination with downstream breakers to isolate faults safely.
