FAP34040 - 40 Amp Circuit Breaker

FAP34040 - 40 Amp Circuit Breaker

Electrical systems can stay in service for decades, even though individual components occasionally need to be replaced. When your circuit breaker fails, most maintenance teams aren't looking to redesign the electrical system—they simply need a replacement that matches the original installation. The FAP34040 is a 40 Amp, 3-pole molded case circuit breaker that helps keep existing equipment operating as intended by providing the same core ratings and connection style required for many established electrical systems.

This breaker uses a thermal-magnetic trip unit to respond to overloads and short circuits, making it a dependable replacement for compatible commercial and industrial applications.
