Square D LAL36400-8041 LAL364008041 - 400A 3 Pole Molded Case Circuit Breaker

The -8041 suffix indicates that the breaker includes factory-installed control wire tapped lugs on both the line and load ends. This allows you to easily tap control power directly from the breaker terminals without modifying the standard lugs.

The factory-installed lugs accept either a single 1 AWG to 600 kcmil conductor or dual 1 AWG to 250 kcmil conductors per phase. They are rated for both aluminum and copper wiring.

This breaker uses a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element. The adjustable magnetic trip allows you to fine-tune the instantaneous short-circuit response to match your specific load requirements.

Yes, in addition to its AC ratings, this breaker is rated for DC applications up to 250V DC. It provides a 10kA interrupting rating at both 125V DC and 250V DC.

This is a unit-mount, feed-thru circuit breaker. It is designed to be individually mounted using hardware in Square D switchboards, panelboards, and motor control centers, rather than plugging onto a bus like an I-Line breaker.

The LAL36400 is the standard interrupting version, rated at 30kA at 480V AC. The LHL36400 is the high interrupting version rated at 65kA at 480V AC, and the LCL36400 is the extra-high interrupting version rated at 100kA at 480V AC. All three share the same physical dimensions and mounting footprint.
