FAQs

The DSD947 J1 J3 S300 is designed as a compatible pilot light cover and device sub-assembly for Eaton/Crouse-Hinds DSD cover systems. It fits standard enclosure openings used in hazardous-area control panels and motor control centers, enabling straightforward replacement without major rework. Ensure mounting hardware matches the DSD accessory specifications and verify clearance for two pilot lights within the enclosure to maintain proper heat dissipation and visibility.
This unit operates at 24 Vdc and features red/green pilot lights with a factory-sealed construction. Certifications include NEC/CEC compliance for Hazardous/Classified Locations, with NEMA ratings 3, 7 and 9. It is suitable for Class I, Division 1 and Division 2, Class II Division 1 and 2, and Class III environments, supporting safe operation in a wide range of hazardous-area applications.
Yes. The DSD947 J1 J3 S300 is designed for Hazardous Area applications and carries NEC/CEC classifications with Class I Division 1 and related divisions, plus NEMA ratings 3, 7, and 9. For oil refinery environments, ensure the enclosure and wiring practices adhere to local codes and that the control panel layout accommodates the two pilot lights and their wiring within the sealed sub-assembly.
Key standards include NEC/CEC compliance for hazardous locations, Class I/II/III ratings, and Division 1 and 2 protections. The device also carries NEMA ratings 3, 7, and 9. Verify that your installation site matches these classifications, and confirm compatibility with the DSD system for a seamless integration into your control panels and enclosures.
Factory sealing minimizes ingress-related maintenance, reducing cleaning and component wear. The two pilot lights enhance visibility, potentially reducing operator errors and downtime. While initial costs may be higher than non-sealed indicators, the long-term maintenance savings, regulatory compliance assurance, and uptime gains in harsh environments typically justify the investment for critical hazardous-area applications.
