FAL340201021 - 20 Amp Circuit Breaker

FAL340201021 - 20 Amp Circuit Breaker

When your breaker with a shunt trip needs to be replaced, getting the right configuration matters just as much as the amp rating. The FAL340201021 is a 20 Amp, 3-pole FA Series molded case circuit breaker with a factory-installed shunt trip, making it a compatible replacement for many existing 480V electrical distribution systems. It's a good choice when you're keeping an existing panel in service and want to preserve the original form, fit, and function, rather than modifying the equipment to accept a different breaker.

Inside the breaker, a thermal-magnetic trip unit handles two different types of faults. The thermal portion reacts when a circuit carries too much current for too long, while the magnetic portion trips almost immediately during a short circuit. Because this model includes a factory-installed shunt trip, it can also be opened remotely via an external control signal, a feature commonly used in emergency shutdown systems and other applications requiring remote operation.
