FA26040BC **Old Style** - 40Amp Circuit Breaker

FA26040BC **Old Style** - 40Amp Circuit Breaker

If you're maintaining an existing I-Line electrical distribution system, the FA26040BC Old Style offers the form, fit, and functional replacement needed for compatible installations. This 40 Amp, 2-pole molded case circuit breaker is built for I-Line plug-in panelboards and features the original B-C phase configuration, making it a practical choice when matching the specifications of an existing system.

Inside, a thermal magnetic trip mechanism responds to both overloads and short circuits to help protect connected equipment and branch circuits. The breaker is rated for 25kA at 240VAC and 18kA at 480VAC, operates on 60Hz systems, and is suitable for environments up to 40°C. It also carries a HACR Type rating for compatible heating, air conditioning, and refrigeration equipment.
