FA24100AC - 100 Amp Circuit Breaker

FA24100AC - 100 Amp Circuit Breaker

Finding the right replacement breaker matters when you're maintaining an existing electrical system. The FA24100AC is a 100 Amp, 2-pole thermal magnetic molded case circuit breaker built for use in compatible I-Line plug-in panelboards. It features the FA frame and is intended as a form, fit, and functional replacement for equipment already in service, helping you keep your existing system configured as originally designed.

With a thermal magnetic trip unit, the breaker responds to both sustained overloads and short-circuit conditions. It carries an interrupting rating of 25kA at 240VAC and 18kA at 480VAC, making it suitable for a variety of commercial and industrial applications within its ratings. This model also features an A-C phase configuration, is HACR Type rated, and is intended for 60Hz systems operating in ambient temperatures up to 40°C.
