The Square D FA22045AC is a molded case circuit breaker from Schneider Electric designed for overcurrent protection in electrical distribution systems. This 2-pole, 1-phase unit operates at 240V with a 45A current rating and provides LI (Long-Time and Instantaneous) protection functions through its thermal magnetic trip mechanism. The breaker features an F Frame size, measures 6.4 in (162.6 mm) x 3 in (76.2 mm) x 4.13 in (104.90 mm) (Height x Width x Depth), weighs 6 lb, and utilizes an I-Line style plug-in connection for secure panel mounting. It complies with industry standards and carries a 10kA interrupting capacity at 240V, making it suitable for commercial and light industrial applications requiring reliable branch circuit protection. This unit is manufactured in Mexico as part of the I-Line family.
