FA26100AB - 100 Amp Circuit Breaker

FA26100AB - 100 Amp Circuit Breaker

The FA26100AB is a 100 Amp, 2-pole thermal magnetic molded case circuit breaker used in compatible FA Series I-Line electrical distribution systems. It's typically installed when an existing breaker needs to be replaced with one that matches the original electrical ratings, mounting style, and A-B phase configuration. Keeping those specifications the same helps you maintain the existing panel layout and avoids unnecessary changes during maintenance or repair. Inside, the breaker uses a thermal-magnetic trip mechanism to respond to both overloads and short-circuit conditions. That combination makes it well suited for your everyday circuit protection in commercial and industrial electrical systems.
