FAQs
Yes. The EIDA3030 S785 is designed as part of Eaton Crouse-Hinds’ EID explosionproof family and fits standard EID enclosure footprints with the switch option. Its dimensions are 10.47 in L, 12.47 in H, 9.65 in W, and it weighs 36 lb, enabling straightforward panel mounting and wiring within hazardous-location installations.
The unit is certified to NEC/CEC standards and carries hazardous-location ratings including Class I Division 1/2, Zone 1/2 and Class II Division 1, along with Class III. It is compatible with NEMA 4/3R/7/9 enclosures, supporting safe operation in outdoor and severe environments.
Ideal for control panels and motor isolation in chemical plants, oil and gas facilities, mining, and other classified locations requiring explosion-protected equipment. The 30A rating and HP range of 5–30 HP suit small to mid-size motors, with 240-600 VAC or 250 VDC supply.
Because it is non-fused with auxiliary contacts (two blocks), you can monitor status signals and interlock logic more reliably. Routine maintenance should include checking enclosure integrity, verifying mounting torque, and testing auxiliary contacts. The copper-free aluminum construction resists corrosion in humid or dusty environments, reducing replacement intervals.
Using a certified explosion-proof disconnect reduces downtime from unplanned outages and streamlines compliance audits. The rugged EIDA3030 S785 supports standard Eaton installation practices, minimizes spare parts, and improves safety, delivering lower total cost of ownership in hazardous-location facilities.
