Westinghouse | RFA3125L | Circuit Breaker | 125A | 3-Pole | 600V

Westinghouse RFA3125L Circuit Breaker delivers reliable protection for demanding electrical systems with a 125A rating across three poles at 600V. Built for maintenance, retrofit, and replacement projects where precise spec matching matters, this 3‑pole breaker keeps three‑phase power distribution safe and uninterrupted.

• Key specifications: Amperage 125A, Poles 3‑Pole, Voltage 600V
• Ideal use cases: replacement in industrial or commercial panels, retrofit projects in existing three‑phase systems, and protection for equipment powered by 600V three‑phase service
• Compatibility you can trust: Part number RFA3125L is the best reference for matching components; always confirm fit and ratings before ordering

The RFA3125L model is designed to integrate with Westinghouse distribution panels and other assemblies that share the same frame and trip characteristics. By selecting the exact 125A, 3‑pole, 600V configuration, you ensure consistent interruptions and predictable performance under fault conditions, helping minimize downtime and protect critical loads.

Practical guidance for planning and installation:

• Verify panel labeling and documentation to confirm the RFA3125L matches your panel’s frame type and trip rating.
• During retrofit, ensure mounting patterns and terminal connections align with existing wiring for a seamless swap.
• For new installations, confirm that a 3‑pole, 600V rating aligns with your three‑phase service and protective device coordination strategy.

In short, Westinghouse’s RFA3125L circuit breaker provides dedicated three‑phase protection with precise 125A capacity, designed to meet the needs of maintenance, retrofit, and replacement projects without compromising safety or performance.
