FA14030B - 30 Amp Circuit Breaker

FA14030B - 30 Amp Circuit Breaker

When you need a compatible replacement breaker for an existing I-Line electrical system, the FA14030B is designed to provide the correct fit and electrical protection. This 30 Amp, 1-pole thermal-magnetic circuit breaker is intended for use on 277/480V AC systems and combines overload and short-circuit protection in a single device. The thermal trip responds to prolonged overcurrent conditions, while the magnetic trip reacts almost instantly to higher fault currents.
