Schneider Electric KC342251021 225A 3-Pole 480 V Circuit Breaker

The Schneider Electric KC342251021 225A 3-Pole 480 V Circuit Breaker is built for demanding industrial environments, delivering dependable protection for large feeders and high-load motors. This 3-pole MCCB (molded case circuit breaker) is engineered to interrupt fault currents quickly while maintaining safe, predictable operation in 480 V three-phase systems.

Why this breaker stands out:

• High-current, three-phase protection: 225 A rating across all three poles ensures balanced protection for every phase, preventing unbalanced faults that could damage equipment.
• Industry-standard 480 V operation: Suited for common industrial distribution voltages, from manufacturing floors to data centers and large HVAC installations.
• Seamless Schneider Electric integration: Part of Schneider’s ecosystem, designed to fit Schneider Electric panels and be compatible with related protection devices, making upgrades and replacements straightforward.
• Reliable thermal-magnetic trip mechanism: Combines fast short-circuit interruption with steady overload protection to minimize downtime and protect downstream equipment.
• Practical field service and maintenance: Built for durable performance and straightforward replacement in existing electrical infrastructure.

Ideal use cases:

• Protect large feeders feeding critical loads in industrial panels.
• Safeguard motors and drives on manufacturing lines.
• Service feeders for data centers, warehouses, and HVAC systems in 3-phase networks.
