Eaton Specification Sheet - FSQC2390
Three-wire, four-pole configuration delivers a robust control interface that minimizes miswiring and inadvertent energization. This translates to improved safety and reliability in harsh environments, and seamless integration with magnetic motor starters in hazardous-area control panels. The copper-free aluminum housing resists corrosion and reduces weight during installation, while brass contacts provide low contact resistance and long-term durability, cutting maintenance costs and downtime. A spring door and through-feed back box enable quick field servicing, simplifying wiring and reducing enclosure openings during routine maintenance. Cable diameter support of 0.39–1.20 inches offers flexibility for varying field cabling while preserving a compact footprint in tight spaces. ANSI/NEMA and NEC/CEC compliance ensure safe operation across Class I/II/III installations, lowering regulatory risk and accelerating project sign-off. The 3/4 inch trade size aligns with standard industrial conduit practices, supporting streamlined procurement and compatible enclosures. The overall rugged construction supports extended service life in demanding environments, delivering measurable ROI through reduced downtime and fewer replacement cycles.
