FA14020A - 20 Amp Circuit Breaker

FA14020A - 20 Amp Circuit Breaker

If you're replacing a compatible breaker in an existing 277/480V AC I-Line electrical system, the FA14020A is designed to match the original form, fit, and function. Rated at 20 Amps with a single-pole thermal-magnetic trip unit, this breaker helps protect branch circuits from both overloads and short circuits. The thermal element responds to prolonged overcurrent conditions, while the magnetic trip reacts quickly when higher fault currents occur.
