Eaton Crouse-Hinds DSD947 J3 J1 SA - NEC Class I

Copper-free aluminum housing and factory sealed construction deliver superior corrosion resistance and long-term reliability in harsh environments, reducing maintenance intervals and total cost of ownership for hazardous-area installations. This translates to improved uptime for critical processes in chemical plants, refineries, and offshore facilities, where panel integrity matters for safety and compliance. Two pilot lights, color-coded green and red, provide immediate status indication, supporting faster operator decisions and reducing shutdown times during commissioning and routine checks. The compact 5.1 in length, 4.2 in height, and 6.5 in width footprint optimizes panel space, enabling easier retrofits and retrofit-ready installations in constrained enclosures without sacrificing visibility. The copper-free aluminum also contributes to lighter assemblies and easier handling during installation, which lowers labor costs and accelerates project timelines. With NEC/CEC alignment and NEMA ratings 3, 7, and 9, this sub-assembly helps ensure regulatory compliance across diverse hazardous-area applications, including chemical processing, mining, and marine environments. The product’s two-pilot-light design supports redundant signaling strategies, improving fault detection and reducing risk of miscommunication in control schemes. Compatibility with standard replacement covers and installation sheets (IF 1424) simplifies stocking and field service, delivering a robust, industry-proven solution for hazardous-location control panels and explosion-protected enclosures.
