Eaton EFSC2190 SA Pushbutton Station - Hazardous Locations
Part Number: EFSC2190 SA
Quick Summary
EFSC2190 SA pushbutton control station is designed to safely operate machinery in hazardous locations. In practice, engineers struggle with choosing enclosures that withstand corrosive atmospheres, meet cross-border compliance, and minimize downtime during maintenance. This unit delivers robust explosion-proof performance with copper-free aluminum housing and two 3/4" hubs, enabling reliable operation in demanding environments. It carries NEC/CEC compliance, and supports hazardous-area ratings including Class I Division 1 and Division 2, Class II, and Class III, plus NEMA 3, 7, and 9 protection. The combination of through-feed wiring, two circuits, and a single-gang footprint simplifies installation and reduces panel space. With 600 Vac rating and universal two-device configuration, it aligns with modern safety standards while supporting future-proof control schemes.
