FH26100AC - 100 Amp Circuit Breaker

FH26100AC - 100 Amp Circuit Breaker

When you're maintaining an existing Square D I-Line™ electrical system, having the correct replacement breaker matters just as much as the electrical rating itself. The FH26100AC is a 100 Amp, 2-pole thermal magnetic circuit breaker designed for 600V AC applications and built specifically for compatible Square D I-Line panelboards and distribution equipment. Because it matches the original form, fit, and function of existing FH-series breakers, it allows electricians to replace aging or damaged breakers without modifying the panel configuration or bus connection.
