FA24015AB **Old Style** - 15 Amp Circuit Breaker

FA24015AB **Old Style** - 15 Amp Circuit Breaker

Finding the right replacement breaker often comes down to matching what's already in the equipment. The FA24015AB Old Style is a 15 Amp, 2-pole thermal-magnetic molded case circuit breaker intended for compatible FA-frame I-Line panelboards and switchboards. When your existing breaker needs to be replaced, using the same frame, pole configuration, and electrical ratings helps keep the original distribution system unchanged.

The FA24015AB Old Style carries an interrupting rating of 14 kA at 480 VAC and 18 kA at 240 VAC. It's also HACR Type rated, allowing it to be used in compatible heating, air conditioning, and refrigeration applications where permitted by code. Built to last, this breaker is intended for maintaining existing equipment where preserving the original installation is the priority—not changing it.
