Square D KC34175G 175A 3-Pole 480 V Circuit Breaker

Square D KC34175G is a 175 A, 3-pole, 480 V circuit breaker engineered for demanding industrial power distribution. This reliable protection device interrupts fault currents to safeguard equipment, reduce downtime, and help maintain safe, continuous operation across three-phase systems.

Built to integrate with Square D panels and distribution setups that run at 480 V, this KC34175G serves as a robust primary feeder for mid-to-large electrical installations. Its 175 A rating provides solid protection for heavy motors, conveyors, compressors, and other high-current loads, while preserving system uptime and safety.

• Three-pole design delivers coordinated protection across all phases, helping prevent phase imbalance and motor damage.
• 480 V voltage rating tailored for industrial environments and equipment that require high-voltage three-phase protection.
• Industrial-grade protection quickly isolates faults, reducing risk to downstream equipment and helping maintain safe operation.
• Replacement-ready part with part number KC34175G, compatible with compatible Square D panels and distribution boards for straightforward maintenance or upgrades.

Common use scenarios include safeguarding large motors and drives in manufacturing lines, protecting HVAC and standby power systems, and securing three-phase feeders in data centers or commercial facilities. If you’re upgrading an existing panel or specifying a new 480 V protection scheme, the KC34175G offers dependable performance with a clear path to installation and service.

Practical tips for maximizing value: confirm panel compatibility with KC-series breakers, ensure secure terminal connections, and coordinate with upstream protection devices to achieve selective tripping and minimize downtime during faults.
