FA26020AB **Old Style** - 20 Amp Circuit Breaker

FA26020AB **Old Style** - 20 Amp Circuit Breaker

When you need a compatible replacement for an existing FA26020AB Old Style circuit breaker, matching the original specifications matters. This 20-Amp, 2-pole FA molded-case circuit breaker is built for use in compatible I-Line plug-in distribution systems and provides thermal-magnetic protection against overloads and short circuits. The Old Style configuration, A-B phase arrangement, and FA frame make it a practical form-fit-and-function replacement in many legacy commercial and industrial electrical systems.

Rated for 25kA at 240VAC and 18kA at 480VAC, the FA26020AB is suitable for a variety of branch circuit protection applications where those ratings are required. It also carries a HACR Type classification for compatible heating, ventilation, air conditioning, and refrigeration equipment. Built for 60Hz systems and rated for operation at ambient temperatures up to 40°C, this breaker is designed to provide dependable protection in demanding electrical environments. Like many molded-case breakers in this product family, it's built to last when installed and maintained correctly.
