FA26050AB - 50 Amp Circuit Breaker

FA26050AB - 50 Amp Circuit Breaker

Finding the right replacement breaker matters, especially when you're maintaining an existing electrical system. The FA26050AB is a 50 Amp, 2-pole FA molded case circuit breaker designed for use in compatible I-Line plug-in panelboards with an A-B phase configuration. Its thermal-magnetic trip unit helps protect circuits from both overloads and short circuits, making it well-suited for keeping existing distribution equipment operating as intended.

With an interrupting rating of 25kA at 240VAC and 18kA at 480VAC, this breaker is built for 60Hz electrical systems and is rated for use in ambient temperatures up to 40°C. It also carries a HACR Type rating, making it compatible with heating, ventilation, air conditioning, and refrigeration equipment.
