Westinghouse | 504C743G23 | Circuit Breaker | 200A | 3-Pole | 600V | Bolt-On

The Westinghouse 504C743G23 circuit breaker is a purpose-built protection solution for 3-phase electrical systems. With 200A capacity, 3-Pole configuration, and a 600V rating, this Bolt-On breaker is designed for reliable, field-ready performance in maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 200 A — scales to protect demanding feeders and distribution circuits without over-tripping in typical commercial environments.
• Poles: 3-Pole — delivers coordinated interruption across all three phases, enhancing fault isolation and system safety.
• Voltage: 600 V — compatible with common 3-phase commercial and light industrial installations.
• Mounting: Bolt-On — secure, robust mounting that suits panels designed for bolt-on protection devices, even in settings with vibration or heavy loads.

This breaker is an ideal match for maintenance, retrofit, and replacement needs where exact specs are required. The part number 504C743G23 serves as the best reference for compatibility, helping you avoid mismatches during component swaps.

Who benefits most

• Electrical technicians performing panel retrofits in Westinghouse-compatible assemblies.
• Facilities managers upgrading protection in 3-phase 600V distribution networks.
• Maintenance teams replacing a failed 200A, 3-pole device with a precise, field-proven equivalent.

Practical use cases

• Retrofit projects where an exact spec match is required to maintain panel cataloging and performance.
• Replacement of aging or damaged breakers in service panels that rely on bolt-on protection components.
• Upgrades in commercial or light industrial settings that demand reliable three-phase interruption at 200A.

Important compatibility note: Confirm fit and ratings before ordering. The 504C743G23 part number is your most reliable reference to ensure seamless replacement in your panel or distribution system.

Installation and care tips

• Use the bolt-on mounting as intended with compatible panels, and follow standard electrical installation practices.
• Engage a qualified electrician to verify correct alignment, mounting integrity, and system protection requirements before energizing.
• Store spare units in a clean, dry environment and handle with care to preserve internal mechanisms.
