Eaton Specification Sheet - EFD318 T8
Compact construction with a built-in switch enables faster installations and reduced panel depth, which lowers wiring complexity and commissioning time in tight control cabinets for conveyors and pumps in hazardous environments. The device is rated for 20 A/30 A and 250 Vac/600 Vac, with 1 hp/2 hp/3 hp horsepower options, providing a versatile motor-control solution that minimizes the number of separate components needed and simplifies spare-parts stock for maintenance teams. Feraloy iron alloy construction delivers durability under demanding conditions, improving arc resistance and long-term reliability in dusty or corrosive environments common to chemical plants and oil and gas facilities. NEC/CEC compliance and hazardous-location ratings (Class I, Division 1/2; Class II, Division 1/2; Class III) coupled with UL/NEMA protection reduce compliance risk and accelerate approval cycles for installations in regulated facilities. The single-gang, 1" trade-size, two-pole dead-end enclosure supports straightforward retrofit and seamless panel integration, aligning with Square D starter families while preserving ease of service and replacement.
