FA26015AB **Old Style** - 15 Amp Circuit Breaker

FA26015AB **Old Style** - 15 Amp Circuit Breaker

The FA26015AB Old Style is a 15 Amp, 2-pole FA molded case circuit breaker designed as a form, fit, and functional replacement for compatible legacy electrical distribution systems. Featuring an I-Line plug-in mounting style with an A-B phase configuration, this breaker is intended for installations that require these exact mechanical and electrical characteristics. Its thermal magnetic trip unit helps protect your branch circuits by responding to sustained overloads through its thermal element while providing instantaneous protection against short circuits with its magnetic trip mechanism. Rated for 25kA at 240VAC and 18kA at 480VAC, the FA26015AB Old Style is suitable for applications that match those interrupting capacities.
