Quick Summary

Eaton Crouse-Hinds EFS2190 ST pushbutton control station provides safe operator control in hazardous locations. In challenging plant environments, standard control stations can risk ignition and noncompliance; this unit mitigates those risks with explosionproof enclosure design and robust certification. It carries NEC/CEC compliance and hazardous-location classifications including Class I Division 1 and 2, Class II Division 1 and 2, Class III, plus a NEMA 3/7/9 enclosure. For engineers and maintenance teams, the combination of a compact single-gang footprint, two pushbuttons, and a 600 Vac rating translates to faster integration, reduced wiring complexity, and lower lifecycle costs for hazardous-area applications.
