Square D KAL3625022M - 250 A, 3-Pole Circuit Breaker | AmpState

Meet the Square D KAL3625022M from AmpState—a 250 A, 3-pole molded-case circuit breaker designed for durable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. With a compact molded-case design and a thermal-magnetic trip unit, this breaker delivers stable, repeatable protection for demanding electrical environments.

Why this breaker stands out

• High-capacity, space-efficient solution: 250 A rating in a compact molded-case form factor helps maximize panel space without sacrificing protection.
• Thermal-magnetic protection: The thermal element handles normal overloads while the magnetic component provides fast, reliable short-circuit tripping, ensuring equipment and conductors stay safe.
• Three-pole configuration: Suited for 3-phase systems, enabling simultaneous disconnection of all hot legs for safer maintenance and code compliance.
• OEM-compatible: Designed to pair with matching Square D OEM load centers and panelboards for proper fit, mounting, and electrical coordination.
• Versatile applications: Ideal for residential, commercial, and light industrial settings where robust branch-circuit protection is required.

Ideal use cases

• Main feeder or subfeed protection in commercial panelboards hosting three-phase equipment like motors, compressors, and HVAC systems.
• Protection for large branch circuits in light industrial environments where reliable interruption of fault currents is critical.
• Installation in service panels that demand coordinated protection with other Square D devices to meet electrical codes and safety standards.
