Square D LGL36600U31X Molded Case Circuit Breaker

This breaker has a standard 80% continuous current rating. It does not carry the C suffix required for a 100% continuous rating.

It is equipped with a factory-sealed MicroLogic 3.3 electronic trip unit. This standard trip unit provides adjustable Long-Time and Instantaneous (LI) protection functions to help coordinate your electrical system.

Yes, unit mount L-Frame breakers typically include mechanical lugs on both the line and load sides. It uses the AL600LS52K3 lug kit, which accepts two 2/0 AWG to 500 kcmil aluminum or copper wires per phase.

Yes, the PowerPacT L-Frame shares common field-installable internal accessories with the H-Frame and J-Frame, including auxiliary switches, shunt trips, alarm switches, and undervoltage releases.

This is a unit mount circuit breaker designed to be individually mounted on a backpan or mounting plate within an enclosure, motor control center, or switchboard. It is not compatible with I-Line plug-on panelboards.

The second letter G in the part number indicates the interrupting capacity tier. This G-tier breaker delivers 35kA at 480V AC. If your system requires a different fault current rating, Square D also offers D, J, L, and R interrupting tiers in the PowerPacT L-Frame.

Yes, PowerPacT L-Frame circuit breakers feature an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism.

No, the U31X suffix indicates standard Long-Time and Instantaneous (LI) protection. It does not include short-time (S) or ground fault (G) protection. You would need an LSIG trip unit, such as the MicroLogic 6.3, for ground fault capabilities.

Yes, because this specific breaker features a factory-sealed MicroLogic trip unit, it is suitable for reverse connection (backfeeding). PowerPacT L-Frame breakers with field-interchangeable trip units are marked line and load and cannot be reverse fed.
