FAQs
The EFD32104 is designed for a two-gang, dead-end enclosure with bolted/ground joint construction and a 1" trade size. Wiring should follow NEC/CEC guidelines for Class I, Division 1/2 and other relevant classifications. Use proper torque on lugs, ensure proper sealing for the enclosure, and verify compatibility with surrounding equipment to maintain explosion-proof integrity.
The EFD32104 carries NEC/CEC compliance and is rated for Hazardous/Classified Locations with Class I, Division 1/2, Class II Division 2, and Class III protection as applicable. It also aligns with NEMA ratings 3, 7, 9, 12, ensuring suitability for a broad range of environments such as chemical plants, refineries, and mining sites.
Yes. The unit is specified for 120/240 Vac operation and provides a 15 A amperage rating, making it suitable for protecting small feeders and control circuits within standard industrial power distributions.
The bolted/ground joint enclosure provides a tight, secure seal that minimizes ingress in harsh environments, improving long-term reliability. This design supports easier inspection and maintenance, reduces leakage paths for ignition sources, and simplifies retrofits in existing two-gang panels without compromising protection.
Despite a higher initial cost, the EFD32104 offers superior durability in hazardous locations, reducing unplanned outages and maintenance costs. Its robust enclosure, corrosion resistance, and regulatory compliance translate to lower total cost of ownership through fewer replacements, longer service intervals, and streamlined safety documentation for audits.
