Square D FA36100 is a 100A, 600V, 3-pole plug-in molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection inside panelboards and load centers. Built for durable performance in demanding electrical environments, this device is ready to upgrade or replace existing protection with a compact, secure plug-in form factor.
Take advantage of a quick plug-in connection that simplifies installation and minimizes downtime. The FA36100 slides into compatible panelboards and load centers with minimal effort, making replacements or updated configurations straightforward for both field technicians and maintenance teams.
The built-in thermal-magnetic trip unit provides stable, repeatable protection: the thermal element handles gradual overcurrents to prevent nuisance trips, while the magnetic trip responds instantly to short circuits. This combination helps safeguard wiring, equipment, and connected loads from damage and downtime.
Designed to pair with matching Square D OEM load centers and panelboards, the FA36100 offers a precise, secure fit and predictable performance. This compatibility helps ensure consistent protection across your electrical distribution system without aftermarket shims or adapters.
With three poles, this breaker provides coordinated disconnection across all hot conductors in multi-wire or three-phase configurations, enhancing safety and reliability in compact installations and complex electrical layouts.
Ideal for residential upgrades, commercial applications, and light industrial distributions, the FA36100 delivers dependable branch circuit protection for circuits with substantial current demands. Use it wherever you need immediate interruption on fault conditions while maintaining smooth operation of your electrical system.
