Westhinghouse MCP0358CR - 7A, 3-Pole, Circuit Breaker

Meet the Westhinghouse MCP0358CR — a purpose-built 7A, 3-Pole circuit breaker designed to safeguard three-phase systems in demanding industrial and commercial environments. This compact device delivers dependable overcurrent protection for panelboards, switchboards, and control panels, helping you keep motors, drives, and other critical loads running safely and smoothly.

• 3-Pole configuration for true three-phase protection — ensures all three phases disconnect together, simplifying wiring and guaranteeing coordinated protection in panelboards and motor control centers.
• 7A current rating — tuned for small-to-mid size loads and control circuits, providing precise protection without unnecessary trips for normal operation.
• Versatile installation — suitable for panelboards, switchboards, and control panels across industrial, commercial, and OEM applications, making it a reliable drop-in solution in new builds or retrofits.
• Fast, reliable disconnection — designed to respond quickly to overcurrent events, helping prevent damage to wiring, contactors, and connected equipment.
• Durable, purpose-built protection — built to withstand the rigors of distribution panels and motor control environments while preserving long-term service life.

Ideal use cases — deploy the Westhinghouse MCP0358CR in manufacturing lines with 3-phase motors, conveyor systems, or control circuits where compact, dependable protection is essential. It’s an excellent replacement part for legacy panel installations or OEM equipment that requires a precise 3-pole 7A breaker, helping you maintain safety, reliability, and ease of maintenance.

Why this matters — choosing a dedicated 3-pole circuit breaker with a 7A rating reduces wiring complexity and ensures synchronized trip behavior across all phases, which is crucial for protecting motors and control circuits in MCCs and distribution panels. In real-world setups, this means fewer false trips, quicker troubleshooting, and consistent protection aligned with your system’s electrical design.

If you’re upgrading or stocking parts for 3-phase distribution, the Westhinghouse MCP0358CR provides focused, reliable overcurrent protection tailored to your panelboards, switchboards, and control panels—delivering peace of mind for industrial, commercial, and OEM electrical installations.
