Westinghouse | FA2050L | Circuit Breaker | 50A | 2-Pole | 600V | Bolt-On

Westinghouse FA2050L circuit breaker delivers reliable overload protection for demanding panels. This 50A, 2-pole, 600V bolt-on unit is built for maintenance, retrofit, and replacement projects where exact compatibility matters. Use the part number FA2050L as your primary reference to ensure a proper fit in Westinghouse- or compatible-rated panels.

• Amperage: 50A
• Poles: 2-Pole
• Voltage rating: 600V
• Mounting: Bolt-On
• Reference: FA2050L (best compatibility indicator)

Why the FA2050L stands out

Designed for dependable protection in commercial and industrial electrical distributions, the FA2050L offers a robust bolt-on mounting system that secures firmly in compatible panels, reducing install time and ensuring solid contact. Its 50A rating makes it ideal for protecting circuits that require higher current protection without sacrificing quick discrimination during fault conditions. The two-pole design guards both conductors in a circuit, helping prevent potential damage and improving overall system safety.

Ideal use cases

• Maintenance, retrofit, or replacement projects where exact FA2050L compatibility is essential
• Westinghouse- or compatible-panel installations that require 50A, 2-pole protection up to 600V
• Industrial or commercial electrical distributions needing reliable, readily serviceable bolt-on breakers

Practical installation and compatibility notes

Before ordering, confirm fit and ratings to avoid mismatches. The FA2050L is the best reference for compatibility, so cross-check the part number against your panel’s documented requirements. When installing, ensure the panel is suitable for 600V operations and that the mounting hardware aligns with the bolt-on design for secure, code-compliant connection. If you’re replacing an existing bolt-on unit, align the breaker to the same lug configuration and ensure the conductor terminations match the panel’s specifications.

Who benefits most

This breaker is particularly well-suited for technicians and facility managers responsible for electrical distribution in facilities with Westinghouse or compatible equipment. If you’re upgrading an older panel, stocking spare FA2050L units can streamline maintenance calls and reduce downtime by providing a ready-fit, high-reliability solution.
