Quick Summary

EDSC3140 SA snap switch control station enables safe, centralized control in hazardous locations. Downtime during maintenance and the challenge of keeping control gear safe in harsh environments often slow commissioning and inflate costs. This unit complies with NEC/CEC standards and carries hazardous-location ratings (Class I, Division 1 & 2; Class II, Division 1 & 2; Class III) along with a NEMA 3,7,9 enclosure. Copper-free aluminum construction reduces weight without compromising durability, while two 1" hubs and a 4-way, four-pole design simplify wiring and future expansion. Designed for engineers and procurement teams, it delivers reliable performance, easier compliance documentation, and a clear path to scalable control architectures.

FAQs

For safe, compliant installation in hazardous locations, use the single-gang, through-feed enclosure with two 1" hubs as specified. Refer to IF 328 installation sheets for EDS, EFS, EDSC and EFSC device bodies to ensure proper mounting, wiring clearances, and gland/NEMA compatibility. Verification of Class I/II ratings and proper wire sizing for 120-277V loads is essential to maintain compliance and performance.
The EDSC3140 SA is rated for 20A at 120-277V. It uses a four-pole, four-way switch arrangement within a copper-free aluminum enclosure, designed for through-feed wiring. This combination supports high-load control while preserving wiring flexibility and panel space, making it suitable for motors and line-control in hazardous environments.
Yes. The EDSC3140 SA provides NEC hazardous-location ratings including Class I, Division 1 and Division 2, plus Class II and Class III designations. Its enclosure is designed for hazardous-location service, helping ensure safe operation and compliance in chemical plants, refineries, and other demanding facilities.
The unit adheres to NEC/CEC standards and features hazardous-location classifications, with a NEMA rating of 3, 7, and 9. Documentation and UL-related certification references are available through provided catalogs and UL profiles. This supports regulatory compliance, safer commissioning, and predictable maintenance in regulated industries.
Copper-free aluminum reduces corrosion and weight, lowering maintenance effort and lifecycle cost. The through-feed wiring and two 1" hubs speed installation, reducing commissioning time and panel space, which translates to faster project timelines and lower total cost of ownership in facilities with frequent line changes or routine servicing.
