FAQs
For Class I, Division 1 installations, mount the EJB120604 SA on a compatible surface or enclosure frame, ensure proper conduit entries and gasket seals, and verify IP66 integrity after wiring terminations. The Style D, no-hinge design speeds access during commissioning while maintaining hazardous-location compliance per NEC/CEC standards.
The enclosure supports a 12" x 6" x 4" footprint with a robust copper-free aluminum body, providing strong mechanical protection while keeping weight manageable. It is compatible with NEC/CEC requirements for hazardous locations and accommodates standard field terminations in space-constrained panels.
The EJB120604 SA carries Hazardous/Classified Location ratings (Class I, Division 1/2 and Zone 1/2), NEMA ratings 3, 3R, 4, 7, 9, and an IP66 ingress protection rating, along with NEC/CEC standards compliance suitable for hazardous industrial environments.
Copper-free aluminum offers superior corrosion resistance, reducing maintenance frequency and replacement costs in harsh environments. The lighter weight also lowers handling and installation effort, contributing to shorter downtime and a lower total cost of ownership in long-term automation and process applications.
