Square D FIL36090 – 90A 3 Pole Molded Case Circuit Breaker Must Have

Part of the legacy F-Frame series, the Square D FIL36090 delivers high-performance overcurrent protection for commercial power distribution. This 90-amp, 3-pole breaker features a thermal-magnetic trip unit with fixed LI functions. It installs into standard Square D switchboards and motor control centers using a unit-mount configuration. For modern upgrades, it is replaced by the PowerPact HRL36090. Rated for 200 kAIC at 480VAC, its current-limiting design minimizes potential fault damage.
