FA36045 - 45 Amp Circuit Breaker

FA36045 - 45 Amp Circuit Breaker

The FA36045 is a 45 Amp, 3-pole thermal magnetic molded case circuit breaker designed for use in compatible I-Line panelboards. Whether you're replacing a worn breaker or maintaining an existing electrical distribution system, choosing a breaker with matching specifications helps preserve the original panel configuration. This FA Series breaker is intended to provide the proper form, fit, and function for compatible legacy installations without requiring changes to the existing equipment. Its thermal-magnetic trip mechanism provides dependable protection by responding to both prolonged overloads and instantaneous short-circuit conditions.
