Square D LE36250LSG Molded Case Circuit Breaker

This breaker features an I-Line plug-on connection, making it compatible exclusively with Square D I-Line panelboards and switchboards. The line side plugs directly into the panel bus, while the load side uses standard mechanical lugs.

No. This is an L-frame breaker with an I-Line plug-on connection. It is strictly designed for Square D I-Line power panelboards and will not mount in NQ, NF, or QO series panels.

The factory lugs accept 2 AWG to 500 kcmil aluminum wire or 2 AWG to 600 kcmil copper wire. Always ensure proper torque specifications are followed during installation to prevent thermal issues.

No. The I-Line mounting style features built-in plug-on jaws that attach directly to the busbar stack in an I-Line panelboard. A retaining bracket is typically included with the panelboard interior to secure the load side of the breaker.
