Square D KC24125AC 24125A 2-Pole 480 V Circuit Breaker

Discover reliable, high-volt protection with the Square D KC24125AC 24125A 2-Pole 480 V Circuit Breaker. Built for demanding industrial environments, this KC-series breaker is engineered to safeguard your 480-volt power distribution, shutting down both conductors together for safer, more predictable protection of feeders, motors, and transformers.

• Part Number: KC24125AC
• Current rating: 24125 A
• Poles: 2
• Voltage rating: 480 V

Why a 2-Pole design matters: when overcurrent or a fault occurs, the KC24125AC disconnects both hot legs simultaneously. This coordinated shutoff minimizes electrical stress, reduces arc potential, and helps ensure safe protection of multi-wire circuits and high-voltage feeders in industrial panels and switchgear. For installations running at 480 V, having a dedicated 2-pole breaker simplifies wiring, improves fault clearance, and supports reliable motor and equipment protection.

Ideal use cases

• Protections for 480 V motor control centers, MCC feeders, and high-voltage distribution panels
• feeders to industrial equipment such as chillers, compressors, and large pumps
• Backup protection within commercial or manufacturing power distribution enclosures that require Square D KC-series compatibility

Key benefits of choosing the Square D KC24125AC include:

• Consistent protection characteristics: Designed to deliver predictable interruption behavior in high-voltage environments, helping to reduce downtime and maintenance complexity.
• Simplicity in integration: Built to fit Square D KC-series panels and assemblies, facilitating straightforward installation and panel compatibility.
• Targeted protection for high-voltage circuits: Specifically suited to 480 V systems, enabling safer and more efficient distribution of industrial power.

Practical considerations and tips

When deploying the KC24125AC, ensure it aligns with your panel design and the connected load. Verify that the ampere rating corresponds to the protection needs of the circuit it feeds, and consult the relevant data sheets or installation instructions for mounting, wiring, and interchangeability within KC-series enclosures. Regularly inspect for signs of wear or tripping events and replace as needed to maintain reliable protection for your high-voltage distribution network.
