FAQs

EDS218 SA fits a single-gang footprint with a 3/4" hub, suitable for compact control panels. Its copper-free aluminum enclosure reduces weight while maintaining strength, and the 120–277V, 20A rating supports common plant loads. Ensure clearance per enclosure guidelines and route wiring through the hub to maintain the hazardous location integrity.
The EDS218 SA is rated for Hazardous/Classified Locations with NEC/CEC compliance and NEC hazardous ratings covering Class I Division 1 and 2, Class II Division 1 and 2, and Class III. The NEMA 3, 7, 9 enclosure provides proven protection against dust, water, and specific chemical exposures typical in hazardous plants.
Key specs include a 20A amperage rating and a voltage range of 120–277V AC. The unit is a two-pole, with a dead-end, 3/4" hub, and a single-gang enclosure that houses two pushbuttons. Plan wiring for a 1-device, 2-pushbutton configuration in a control station scenario.
Installation sheets IF 242 for EDS/EDSC control stations and the Eaton specification sheet for EDS218 SA provide step-by-step wiring, mounting, and safety guidance. Useful PDFs include the IF 242 instruction sheet and the EDS218 SA specification sheet available on Eaton’s site and linked catalog pages.
The copper-free aluminum construction and robust enclosure minimize corrosion-related downtime, extending service life in harsh environments. Certified hazardous location ratings reduce regulatory risk, while streamlined wiring and two-pushbutton operation shorten commissioning time, lowering total cost of ownership and improving return on investment over the life of the installation.
