Square D | KCP24150 | Circuit Breaker | 150A | 2-Pole | 480V

The Square D KCP24150 Circuit Breaker is a rugged 150-amp, two-pole protective device designed for 480-volt electrical systems. Engineered for reliability in maintenance, retrofit, and replacement projects, this breaker ensures your 480V circuits stay protected with precise trip coordination and durable performance. The part number KCP24150 is the key reference for identifying the right fit, so matching this exact specification is essential for compatibility.

Key specifications

• Amperage: 150A
• Poles: 2-Pole
• Voltage: 480V

Fit, compatibility & ordering tips

To ensure a correct match, verify the exact part reference (KCP24150) and confirm the device is intended for 480V, 150A, 2-pole service. This breaker is designed for Square D panels and similar systems that use compatible frame and rating specifications. Before ordering, double-check panel labeling and any upstream protective devices to maintain proper coordination and code compliance.

Ideal use cases

• Industrial maintenance cycles where existing protection must be preserved without recalibrating downstream equipment.
• Retrofit projects that upgrade or replace aging switchgear in 480V distributions.
• Spare or replacement parts for 480V dual-leg circuits in manufacturing lines, HVAC systems, and large motors.
• New installations requiring a robust 150A, 2-pole breaker to reliably interrupt both hot legs simultaneously.

What makes this 150A, 2-Pole 480V breaker stand out

By delivering dual-leg protection at a high current with a trusted Square D design, the KCP24150 helps limit arc fault exposure and protects connected equipment from overloads. The 2-pole configuration ensures simultaneous tripping of both hot conductors, which is critical for maintaining circuit integrity in high-load 480V environments. Its build and engineering are purpose-built for industrial panels where consistent performance, availability of spare parts, and straightforward cross-reference with existing KCP-series components matter most.

Practical tips for installation and care

• Always power down and lockout-tagout the circuit before replacement or installation.
• Inspect the panel and bus connections for signs of wear or damage; replace any worn components to ensure reliable operation.
• Keep a spare KCP24150 on hand for proactive maintenance and to reduce downtime during outages or service windows.
• Document the change with the exact part number to aid future repairs and audits.
