Why this 2-pole 480V breaker matters in your facility

In industrial power systems, protecting both conductors of a 480 V circuit is essential for safe operation and equipment longevity. The KC24150BC’s 2-pole design ensures coordinated interruption across the two hot legs, which is crucial for machinery, conveyors, and other high-demand loads commonly found in manufacturing, processing, and distribution environments. This breaker is particularly well-suited for service panels, equipment disconnects, and replacement projects where reliability and fast fault clearing are non-negotiable.

Ideal use cases

• New installations in 480 V distribution networks across manufacturing floors, process plants, and industrial facilities
• Replacement of aging or failing breakers in control panels and service disconnects
• Upgrades to higher-capacity protection for heavy machinery and motor-driven equipment
• Maintenance projects requiring a direct-fit Square D part with verified compatibility by part number

How this breaker fits into your installation plan

• Verify fit by part number KC24150BC and align it with your application requirements before purchase
• Ensure your panel or switchgear is rated for 480V and supports a 150 A, 2-pole breaker
• Follow manufacturer guidelines for wiring, torque, and clearance to maximize reliability and safety
• Consider the specific load profile—heavy motor loads, conveyors, or processing lines—and confirm this breaker’s capacity matches protective needs
