Schneider Electric FCP34100MT U Circuit Breaker

Schneider Electric's Square D FCP34100MT U is a three‑pole molded‑case circuit breaker rated for 100 A at 480 V AC, designed to protect feeders and motor circuits within commercial and industrial power distribution panels. It belongs to the FCP series and provides thermal‑magnetic overcurrent protection with distinct long‑time and instantaneous trip functions, and it terminates on the load side with lug connections for straightforward wiring. The unit is bolt‑on mounted in compatible panels and specifies a 65 kA interrupting rating at 480 V, delivering fault‑current protection appropriate for many distribution arrangements. As of current availability, FCP34100MT U is considered obsolete and is typically found only in used inventories or remaining stock from suppliers. This makes it a niche choice for legacy installations or replacements where an exact FCP family component is required to maintain historical panel configurations.
