FAQs
The DSD948 J1 LED T4 is designed to fit standard DSD cover and device sub-assemblies. Ensure the enclosure is rated for Hazardous/Classified Locations, connect the 440-480 Vac supply to the transformer input, and mount the unit per Eaton’s IF899 installation guidelines. Verify the pilot light, wiring clearances, and sealing integrity after installation to maintain NEMA and NEC/CEC compliance.
Key specifications include a 440-480 Vac voltage rating, Red LED indicator, built-in transformer, and a single pilot light configuration. The device is factory sealed and uses Feraloy iron alloy housing for rugged operation. These details support reliable signaling in hazardous locations, meeting NEC/CEC standards and corresponding NEMA ratings 9, 7, and 3.
Yes. The DSD948 J1 LED T4 is certified for Hazardous/Classified Locations with NEC/CEC standards and NEMA ratings compatible with Class I, II, and III installations. Its factory sealing and robust housing make it suitable for chemical processing, oil and gas refining, and other high-risk environments where safe, visible signaling is critical.
The unit supports NEC/CEC compliance and Hazardous/Classified Locations area classifications, with NEMA ratings 9, 7, 3. Certification references include UL-based documents for explosion-proof sub-assemblies. These certifications simplify regulatory approvals, expedite procurement, and reduce risk for global projects involving hazardous-area signaling.
LED signaling offers longer life and lower energy use than incandescent options, while factory sealing minimizes ingress-related failures. The combined effect is fewer maintenance intervals, lower replacement costs, and improved uptime for critical control panels in demanding environments, translating to reduced total cost of ownership and faster ROI on automation upgrades.
