Square D FCL34100 – 100A 3 Pole Molded Case Circuit Breaker Affordable

Designed for heavy-duty commercial applications, this 100-amp F-Frame breaker restricts let-through energy to shield downstream equipment from severe faults. It installs into standard Square D enclosures, switchboards, and motor control centers using unit-mount lugs. Featuring a 65kAIC rating at 480VAC, the thermal-magnetic unit includes a visual trip indicator and HACR certification. Note that this legacy component has been superseded by the HJL36100 for newer installations.
