Westinghouse | RFA3150L | Circuit Breaker | 150A | 3-Pole | 600V | Bolt-On

Westinghouse RFA3150L is a bolt-on circuit breaker engineered for reliable overcurrent protection in 600V electrical systems. With a 150A rating and three poles, this unit is purpose-built for panel configurations that require a robust, secure bolt-on connection during maintenance, retrofit, or replacement projects.

Core specs at a glance

• Amperage: 150 A
• Poles: 3-Pole
• Voltage: 600V
• Mounting: Bolt-On
• Part number: RFA3150L

Why choose the Westinghouse RFA3150L?

Unlike plug-in alternatives, the bolt-on design provides a solid, electrically secure connection that withstands vibration and routine panel maintenance. The 3-pole configuration protects three phase conductors, making it suitable for 600V distribution networks where balanced protection is essential. The 150A rating makes it ideal for feeders and line-side protection in commercial or industrial environments.

Who is this for?

Perfect for electrical maintenance teams, retrofit specialists, and replacement projects where exact specs matter. If you're upgrading an existing panel or replacing a worn-out breaker, confirm that your equipment matches the RFA3150L reference to ensure compatibility.

Compatibility and installation notes

Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility. This breaker is designed for bolt-on mounting in compatible panels—ensure your enclosure supports three-pole, 600V, 150A bolt-on devices before purchasing.

Practical tips and use cases

• Use during panel retrofit projects where a secure, bolted connection is preferred for long-term reliability.
• Ideal for load feeders in 3-phase, 600V systems where consistent protection across all phases is required.
• Keep a record of the RFA3150L part number for quick replacement if a breaker needs swap-out in the future.
