Westinghouse | RFA2040 | Circuit Breaker | 40A | 2-Pole | 600V | Bolt-On

Meet the Westinghouse RFA2040 Circuit Breaker — a purpose-built solution for dependable overcurrent protection in demanding electrical panels. With a 40A rating, 2 poles, and a 600V design, this bolt-on breaker is engineered for quick, secure installations during maintenance, retrofit, or replacement projects.

• Amperage: 40A
• Poles: 2-Pole
• Voltage: 600V
• Mounting: Bolt-On
• Part number: RFA2040

The RFA2040 is a precise fit for systems that require exact specifications. Its bolt-on mounting enables a solid, straightforward installation, helping reduce downtime during panel maintenance or upgrades. When you’re upgrading aging equipment or performing a routine retrofit, this breaker provides the trusted protection you need without compromising on reliability.

Ideal use cases

• Maintenance or replacement in existing panels that accept 2-pole, 600V breakers should consider the RFA2040 for a seamless fit.
• Retrofits where circuit loads are updated or where compliance with current requirements is needed.
• Spare or aging-asset replacement in commercial or light-industrial installations that rely on Westinghouse components.

Why this part matters

Choosing the RFA2040 isn’t just about matching numbers — it’s about reliable, predictable protection for your circuits. The 40A rating protects conductors from overloads, while the 2-pole design ensures both live conductors disconnect simultaneously, enhancing safety in shared-neutral or multi-wire applications. The 600V rating supports a range of higher-voltage environments, giving you flexibility as your system evolves.

Important compatibility note

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility. Always verify that the panel and enclosure are designed to accept RFA2040-series breakers to ensure safe and compliant operation.

Practical tips for installation and long-term use
