FAL341001021 - 100 Amp Circuit Breaker

FAL341001021 - 100 Amp Circuit Breaker

The Square D FAL341001021 is a 100 Amp, 3-pole FA Series molded case circuit breaker with a factory-installed shunt trip for compatible 480 VAC electrical systems. This breaker is typically selected when an existing installation already uses a shunt trip accessory and the replacement needs to match the original equipment configuration.

With its unit-mount design, AL100FA terminal configuration, and line and load lug connections, the FAL341001021 is made for compatible FA Series applications. It provides the same key specifications maintenance teams look for when you're replacing an existing breaker, without requiring changes to the surrounding electrical equipment. Built to last, this breaker is a dependable fit for established commercial and industrial systems.
