Schneider Electric NSB FHL36090 Molded Case Circuit Breaker

Schneider Electric's Square D FHL36090 molded‑case circuit breaker is a three‑pole MCCB rated for 90 A at up to 600 V, part of the FHL family designed for branch protection in electrical distribution panels. It provides thermal‑magnetic overcurrent protection for three‑phase circuits, with a compact trip assembly and standard lug/terminal connections suitable for common industrial wiring practices. Key specifications include a 90 A continuous current rating, a 600 VAC nominal voltage rating, and a thermal‑magnetic trip mechanism that responds to overloads and short circuits. The FHL series is intended for use in commercial and light industrial installations where precise overcurrent protection is required across three phases, including motor circuits, processing equipment, and power feeders in panelboards and switchgear. When integrated into a panel, it supports typical MCCB accessories and mounting arrangements used with Square D/Schneider Electric devices to ensure proper protection coordination with upstream and downstream equipment in a distribution scheme. This model is commonly cataloged as FHL36090 and is widely stocked by electrical distributors, making it a standard choice for replacement and retrofit projects requiring a 90 A, 3‑pole, 600 V MCCB from Schneider Electric.
