Square D LAL26225 Molded Case Circuit Breaker

The magnetic trip on the LAL26225 is adjustable from 1125A on the low setting to 2250A on the high setting.

No, the LAL26225 is a standard-rated circuit breaker. Per standard electrical codes, it is designed to carry up to 80 percent of its 225A rating (180 Amps) for continuous loads that operate for three hours or more.

Yes, the factory-installed AL400LA lugs allow for dual wire connections. You can terminate two 1 AWG to 250 kcmil aluminum or copper wires per phase, which is useful for parallel conductor runs.

No, the LAL26225 is a unit mount circuit breaker designed for bolt-on or base-mounted applications. It does not have the plug-on jaw connections required for Square D I-Line panelboards.

The LHL26225 is the high interrupting equivalent of the LAL26225. Both share the same physical dimensions and L-frame footprint, but the LHL series provides higher short circuit protection for systems requiring a higher AIC rating.

The Square D PowerPact series, specifically the J-frame or L-frame, serves as the modern replacement for legacy L-frame breakers. Note that upgrading to a PowerPact breaker may require different mounting hardware or enclosure modifications.

The magnetic trip dial on the front of the breaker should be set based on the specific inrush current of your load. It must be set high enough to prevent nuisance tripping during startup, but low enough to provide reliable short circuit protection.
