Square D FDA32100 – 100A 3 Pole Molded Case Circuit Breaker Low Price

Part of the legacy F-frame lineup, this 100A molded case circuit breaker delivers thermal-magnetic protection for commercial distribution systems. It features fixed long-time and instantaneous (LI) trip functions to handle standard overcurrent events. The unit mounts into Square D I-Line panelboards and switchboards using a secure plug-on jaw connection. For facility upgrades, it serves as an exact match for older F-frame slots and is officially replaced by the newer QDA32100 series.
