Westhinghouse MCP0322S - 3A, 3-Pole, Circuit Breaker

Westhinghouse MCP0322S is a compact, reliable 3A, 3-pole circuit breaker designed to deliver dependable overcurrent protection in three‑phase systems. Built for panelboards, switchboards, and control panels, it keeps equipment safeguarded in demanding industrial environments.

• Three-pole protection protects all three hot legs (L1, L2, L3) simultaneously, helping prevent phase imbalance and motor damage in 3‑phase circuits.
• Precise 3A rating provides targeted protection for small to medium control circuits and auxiliary feeds within distribution panels and MCCs.
• Flexible deployment Ideal for industrial, commercial, and OEM applications where dependable overcurrent protection and safe operation are critical in panelboards, switchboards, and motor control centers.
• Durable, code-friendly design engineered to perform reliably in harsh environments where consistent protection is essential for uptime and safety.

In practice, the MCP0322S helps maintenance teams and panel builders design safer, more resilient electrical assemblies. Use it in three‑phase control panels for conveyors, pumps, fans, and other MCC‑level equipment, where a single three-pole device ensures all phases trip together and protects the entire circuit. It’s a practical choice for OEMs seeking a dependable, space-efficient solution that aligns with standard three‑phase infrastructure.

Key benefits

• Consistent protection across all three phases, reducing the risk of partial faults and equipment damage.
• Clear, actionable current rating that matches small‑scale control circuits and auxiliary feeders without over-tripping.
• Simple integration into existing 3‑phase panel builds, accelerating assembly and serviceability.

Whether you’re refreshing an aging control panel or engineering a new motor control solution, the Westhinghouse MCP0322S delivers focused, reliable protection where you need it most—on every phase of your three‑phase system.
