FA14015B - 15 Amp Circuit Breaker

FA14015B - 15 Amp Circuit Breaker

The FA14015B is a 15 Amp, 1-pole thermal-magnetic circuit breaker designed for use in compatible 277/480V AC I-Line electrical distribution systems. It provides both overload and short-circuit protection through a combination of thermal and magnetic trip mechanisms, helping protect branch circuits and connected equipment during normal operation and fault conditions. With its I-Line connection on the line side and lug terminals on the load side, this breaker installs in compatible I-Line panelboards and switchboards without requiring changes to the existing system. Whether you're replacing a worn breaker during routine maintenance or servicing an existing electrical distribution system, the FA14015B offers the correct form, fit, and function for compatible applications.
