Square D LAL36250 - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

Square D LAL36250 is a rugged 3-pole molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a 250 A rating and a 600 V maximum voltage, this device is built to handle demanding commercial and light industrial environments while staying compact enough to maximize panel space.

Key differentiators you’ll feel in everyday use

• Compact molded case design saves precious space in crowded panels without sacrificing protection or performance.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining overload (thermal) and short-circuit (magnetic) trip mechanisms for predictable response to faults.
• 3-pole configuration ensures synchronized protection across three-phase systems, preventing imbalanced faults and equipment damage.
• OEM panel compatibility is designed to work with matching Square D load centers and panelboards for seamless integration and labeling.
• Versatile applications suitable for residential, commercial, and light industrial installations where dependable protection is essential.

How this breaker solves real problems

• Protects heavy feeders and branch circuits from overcurrent conditions, reducing the risk of insulation damage and fire in electrical panels.
• Provides rapid short-circuit isolation with a trip curve that responds quickly to high fault currents, minimizing equipment downtime.
• Delivers consistent performance across varying loads, helping maintain stable electrical distribution in ever-changing environments.
• Fits neatly into planned panel layouts thanks to its compact form factor, helping maintain clear labeling and easier maintenance visits.

Ideal use cases

• Main or feeder protection in commercial panelboards and load centers handling three-phase loads.
• Branch-circuit protection for equipment rooms, light industrial machinery, and large-power circuits requiring a 250 A disconnect.
• Retrofits or upgrades in existing Square D systems where OEM compatibility ensures smooth, documented replacement coverage.
