Eaton EFSC3190 Pushbutton Control Station - Class I Div 1
Part Number: EFSC3190
Quick Summary
EFSC3190 pushbutton control station enables safe start/stop control in hazardous industrial locations. In many plants, rugged environments and strict codes challenge reliable operation, wiring routing, and component protection. This unit is designed for Class I Div 1 hazardous locations and offers NEC/CEC compliance with additional protections for Class II and Class III environments, plus NEMA ratings 3, 7, and 9. By combining a two-button, two-device configuration in a single-gang, through-feed enclosure, it reduces panel depth and installation time. The result is lower maintenance costs and faster commissioning, while preserving flexibility for future control changes in heavy-industrial settings.

Explosion-proof construction using Feraloy iron alloy provides rugged enclosure protection that minimizes downtime in harsh environments. Business impact: improved equipment longevity and safer operation in chemical plants and oil/gas facilities. Application: installation in hazardous areas where mechanical wear and exposure to corrosive atmospheres are common. Dual pushbuttons and two devices within a single-gang enclosure streamline control circuits, reducing panel space and wiring complexity. Business impact: faster wiring, simpler maintenance, and room for future control logic changes. Application: start/stop control paired with pilot signaling in compact layouts. Through-feed design with two 1" hubs enables flexible field wiring and conduit routing, shortening commissioning time. Business impact: lower labor costs and easier relocation of devices during plant upgrades. Application: installations with demanding conduit layouts in mining or refining operations. NEC/CEC compliance plus Class I Div 1, II, and III ratings and NEMA 3/7/9 protection deliver regulatory readiness and safer operation. Business impact: faster regulatory approvals and reduced risk of non-compliance. Application: diverse hazardous-location projects requiring certified equipment. Compatibility with EDS/EFS family design packages and installation guides supports rapid deployment and standardized maintenance. Business impact: consistent performance across fleets and lower total cost of ownership. Application: engineering teams seeking proven, upgrade-friendly control station solutions.

FAQs
Begin by isolating power, mount the EFSC3190 in a single-gang enclosure, and route field wiring through the two 1" hubs using through-feed configuration. Use appropriate conduit and seals for hazardous locations, then connect the two pushbuttons and two devices per the control scheme. Verify proper enclosure integrity and verify ratings (Class I Div 1, NEC/CEC) before energizing the circuit.
EFSC3190 carries NEC/CEC compliance with Class I Division 1, Class I Division 2, Class II Division 1 and 2, and Class III ratings, along with NEMA 3, 7, and 9 protection. These certifications confirm suitability for hazardous locations and demanding industrial environments, simplifying compliance during project approvals.
EFSC3190 is designed as a single-gang through-feed control station featuring two pushbuttons and two devices. It provides compact integration within a single-gang footprint, while offering the through-feed capability necessary for flexible wiring. For larger control schemes, consider coordinating with compatible EFS family assemblies to maintain certified protection.
The unit uses a Feraloy iron alloy enclosure, engineered for high-strength, explosion-proof performance in hazardous environments. The enclosure is specified as through-feed with two 1-inch hubs and two pushbuttons, supporting reliable operation in challenging industrial settings such as chemical plants, refineries, and mining operations.
Downloads include 3D design packages and installation sheets relevant to EFSC and related explosion-proof stations. Look for SP3D design packages, IF 328/IF 899 instruction sheets, and the Eaton specification sheet for EFSC3190 to guide mounting, wiring, and regulatory compliance during deployment.
