Eaton EFSC2190 ST SP Pushbutton Station - Hazardous
Part Number: EFSC2190 ST SP
Quick Summary
EFSC2190 ST SP pushbutton control station is a rugged device designed for hazardous locations. In many industrial plants, operators struggle with protecting control interfaces from dust, moisture, and arc events while keeping downtime to a minimum. It meets NEC/CEC compliance and hazardous-location ratings, including Class I/II/III, Division 1 and 2, with a robust NEMA 7/9/3 enclosure. With a 600 Vac rating, two pushbuttons, and through-feed wiring, installation is faster and more reliable. The result is safer operation, reduced maintenance, and predictable performance, supporting ongoing production goals with through-life reliability for oil and gas, mining, and chemical processing facilities.

Eaton Specification Sheet - EFSC2190 ST SP
Explosion-proof enclosure with a feraloy iron alloy body delivers ignition protection and rugged durability. This reduces the risk of internal arcs and external damage, which translates to safer operation and lower maintenance costs for hazardous-location motor controls used in chemical plants and refineries. Through-feed mounting, two 3/4" hubs, and a two-pushbutton/two-device arrangement simplify conduit connections and wiring, cutting installation time and panel footprint in tight automation environments. The 600 Vac rating supports high-voltage control circuits, enabling single-device control of motors and pumps without adding devices or adapters, which lowers parts inventory and downtime. NEC/CEC compliance and hazardous-location ratings (Class I, II, III; Division 1/2) with a NEMA 7/9/3 enclosure provide formal safety assurance for regulated facilities such as refineries and mining. Clear Start/Stop indicating plates improve operator literacy and reduce misoperation, while a single-gang enclosure minimizes panel space usage and simplifies retrofits in existing control panels. Built for durability, the unit withstands arc, vibration, and environmental stress, delivering long-term lifecycle value and lower total cost of ownership for maintenance teams and project engineers.

FAQs
EFSC2190 ST SP is designed for hazardous locations, offering NEC/CEC compliance and hazardous-location ratings that cover Class I, II and III environments with Division 1 and 2 options. The device incorporates a rugged through-feed enclosure and NEMA-rated protection to ensure safe operation in chemical plants, refineries, and mining operations.
EFSC2190 ST SP supports two pushbuttons and two devices within a single-gang enclosure. It features two 3/4" hubs for through-feed wiring, simplifying conduit connections and reducing installation time while delivering compact, reliable control for motor and pump circuits up to 600 Vac.
Yes. The EFSC2190 ST SP is designed as an explosion-proof control station using a feraloy iron alloy enclosure to provide ignition protection, meeting hazardous-location requirements and enabling safe operation in volatile environments such as chemical plants and oil refineries.
It complies with NEC/CEC standards for hazardous locations, offers NEC Class I/II/III, Division 1/2 ratings, and is packaged in a NEMA 7/9/3 enclosure. UL certification details are available in Eaton’s documentation, and the unit is suited for use in regulated industrial facilities requiring robust safety compliance.
Plan for through-feed wiring with two 3/4" hubs and a single-gang enclosure to minimize wiring complexity. Use the 600 Vac rating for high-voltage control circuits, and position the Start/Stop indicating plates clearly. The feraloy body and rugged enclosure support operation under vibration, dust, and moisture, reducing maintenance and extending equipment life.
