FAQs
Installation requires a Size 1 clamped enclosure designed for hazardous locations, with copper-free aluminum construction and a three-pole configuration. Verify the enclosure is rated for NEC/CEC and Zone/Class classifications, confirm 600 VAC voltage, and ensure the 50 AIC interrupt rating matches your protection scheme. The clamped cover simplifies access for routine maintenance while preserving enclosure integrity in demanding environments.
The EBMX1B-W050 provides 600 VAC voltage rating and a 50 AIC interrupt rating, arranged in a three-pole configuration. This combination supports robust protection for high-power circuits such as motors and feeders in hazardous locations. The design aligns with NEC/CEC requirements, ensuring reliable performance, safe disconnection, and compliance during audits and inspections.
Yes. It is well suited for industries facing hazardous-location challenges such as oil & gas, chemical processing, mining, and heavy manufacturing. Its explosionproof clamped EBMXB design, Size 1 enclosure, and 600 VAC rating enable safe power distribution for critical equipment, while NEC/CEC compliance and NEMA ratings support cross-industry adoption and regulatory acceptance.
The EBMX1B-W050 carries NEC/CEC compliance with hazardous-area ratings (Class I, Division 1 & 2; Zone 1 & 2) and Class II/III listings, along with NEMA ratings 3R, 4X, 7, and 9. Its area classification is Hazardous/Classified Locations, and the enclosure uses copper-free aluminum for corrosion resistance. These certifications support regulatory acceptance and safe operation in demanding environments.
