FA24100BC - 100 Amp Circuit Breaker

FA24100BC - 100 Amp Circuit Breaker

The FA24100BC is a 100 Amp, 2-pole thermal magnetic molded case circuit breaker built for use in compatible I-Line plug-in panelboards. With its FA frame and B-C phase configuration, it provides the correct form, fit, and function for many existing electrical distribution systems. Whether you're replacing a worn breaker during routine maintenance or restoring equipment to service, matching the original specifications is essential for proper operation.

This breaker uses a thermal magnetic trip mechanism that responds to prolonged overloads as well as short-circuit faults. It carries an interrupting rating of 25 kA at 240 VAC and 18 kA at 480 VAC, making it suitable for applications within those ratings. The HACR Type classification also makes it appropriate for compatible heating, air conditioning, and refrigeration equipment.
