Square D KAL361251042 125A 3-Pole 600 V Circuit Breaker

Square D KAL361251042 is a 125 A, 3-pole circuit breaker engineered for reliable protection of three-phase electrical systems up to 600 V. Built by Square D, a trusted name in industrial electrical equipment, this unit fits into compatible Square D panelboards and switchgear, delivering precise interruption of fault currents to safeguard equipment and personnel.

Key features and benefits:

• Three-pole configuration provides simultaneous disconnection of all phases, ensuring balanced protection for three-phase motors, pumps, HVAC units, and feeders.
• 125-amp current rating suits large-draw circuits while allowing fine-grained protection for distribution panels.
• 600 V maximum voltage rating compatible with industrial power distribution networks, including common three-phase systems.
• Reliable, field-tested protection from a leading brand—Square D—designed for rugged environments and long service life.

Where to use:

• Industrial facilities with three-phase equipment (motors, conveyors, pumps) requiring robust feeder protection.
• Commercial buildings with large HVAC or chiller circuits fed from three-phase power.
• Facilities with 3P distribution panels that require a 125 A interrupting device for safe electrical protection.

Why it matters:

• Coordinated trip across all phases reduces equipment stress, limits fault propagation, and helps meet electrical safety standards in your distribution system.
• Using the exact part KAL361251042 ensures consistent performance and panel compatibility, simplifying maintenance and downtime planning.

Installation and compatibility tips:

• Use this breaker in Square D panelboards and enclosures that accept the KAL series 3-pole devices. Always confirm panel compatibility and follow local electrical codes during installation.
• Verify the device’s rating against your system’s voltage, load, and motor starting characteristics to ensure safe, reliable protection.
• Keep a spare KAL361251042 on hand for quicker replacements and minimized downtime in critical facilities.
