Westinghouse | RFA3150 | Circuit Breaker | 150A | 3-Pole | 600V | Bolt-On

The Westinghouse RFA3150 circuit breaker is a rugged, reliable protection device designed for 600V, three‑phase systems. With a 150A rating and a 3‑pole configuration, this bolt‑on unit is built for maintenance, retrofit, and replacement projects where precise compatibility matters.

• Amperage: 150A
• Poles: 3‑Pole
• Voltage rating: 600V
• Mounting: Bolt‑On
• Part number: RFA3150
• Best reference for compatibility: Use the part number to confirm fit

Why a bolt‑on design matters: bolt‑on mounting provides a solid, vibration‑resistant connection in appropriate panelboards, enabling straightforward installation or replacement with minimal downtime. The RFA3150 is especially suited for projects that require an exact mechanical and electrical match to existing Westinghouse panels or compatible systems, helping you preserve wiring layout and protective coordination.

Use cases and practical applications

- Replacement: Swap in the RFA3150 when a 150A, 3‑pole breaker in a 600V system needs dependable protection. - Retrofit: Upgrade aging distribution setups to modern, compatible Westinghouse components without reconfiguring the panel. - Maintenance: Keep commercial or industrial wiring protected with a unit designed to align with established specifications.

Key advantages that set this breaker apart

Unlike generic substitutes, the RFA3150 is a direct reference part identified by its unique number, ensuring exact alignment with specific panelboard architectures. By matching amperage, pole count, voltage, and bolt‑on mounting, you reduce compatibility surprises and maintain safe, reliable operation across your 3‑phase circuit. Remember to confirm fit and ratings before ordering—the part number is your most reliable compatibility reference.

Installation considerations

• Verify your panel supports bolt‑on, 3‑pole breakers at a 150A rating and is designed for 600V operation.
• Consult your panel’s documentation and use the RFA3150 as the compatibility reference when ordering or replacing components.
• Follow all safety and installation instructions from the panel manufacturer and licensed electrical guidelines during the mounting and wiring process.
