Westinghouse FB1020 Circuit Breaker, 20A, 1-Pole, 277V

Westinghouse FB1020 Circuit Breaker, 20A, 1-Pole, 277V is a rugged protection device designed for industrial electrical service, maintenance, and replacement projects. Built to interrupt fault currents quickly and safely, this 1-pole breaker protects single-phase loads operating at 277V, helping you maintain reliable power delivery in demanding environments.

Key benefits

• 20 ampere protection tailored for standard industrial circuits, balancing safety and performance.
• 1-Pole design ideal for single-phase loads common in control panels, lighting systems, and equipment feeds.
• 277V operation suited for commercial and industrial power distribution where higher-voltage circuits are standard.
• Part-number driven compatibility use the FB1020 to confirm fit with your panel and application requirements.
• Reliable, maintenance-friendly replacement simplifies upgrades and service calls, reducing downtime in critical systems.

Why this matters for your project

In industrial settings, downtime is costly. The Westinghouse FB1020 is designed to slot into existing boards where a 1-pole, 20A 277V breaker is specified, enabling quick, exact matches without guesswork. Its construction supports frequent switching and protection for equipment like conveyors, fans, motors, and lighting circuits—areas where consistent performance and predictable tripping behavior are essential.

Use cases

• Replacing a failed or outdated breaker in an industrial control panel
• Protecting 277V lighting circuits in warehouses or manufacturing floors
• Providing a reliable single-pole protection solution for industrial equipment feeds
• Maintenance planning where part-number verification ensures swap-in compatibility
