FA14020B - 20 Amp Circuit Breaker

FA14020B - 20 Amp Circuit Breaker

When you need a compatible replacement for an existing 277/480V AC I-Line electrical distribution system, the FA14020B circuit breaker is designed to provide the same form, fit, and function as the original equipment. Rated at 20 Amps with a single-pole thermal-magnetic trip unit, it helps protect branch circuits against overloads and short circuits. The thermal trip responds to sustained overcurrent conditions, while the magnetic trip reacts quickly to higher fault currents, helping safeguard connected equipment.
