FAQs
The EBMX2B-W125 comes in a Size 2 enclosure with a clamped cover designed for hazardous locations. Ensure proper gland sealing and gasketing as specified in the installation sheets, verify enclosure integrity against ambient conditions, and follow NEC/CEC requirements for Class I Division 1 environments. The copper-free aluminum construction aids corrosion resistance and ease of handling during mounting.
A 125 AIC interrupt rating provides robust arc interruption capability for high-energy faults, improving protection for feeders and motors in hazardous environments. It helps limit fault energy, supports safer shut-down sequences, and aligns with NEC/CEC protection requirements in Class I/Division 1 and Zone 1 installations while maintaining UL-listed conformity.
Yes. The EBMX2B-W125 is specified as explosionproof and is listed for hazardous locations, with NEC/CEC compliance and UL certification relevant to enclosures and equipment used in Class I Division 1 (and related hazardous locations) applications. Always consult the latest Eaton datasheet and UL listings for exact scope and installation guidelines.
This model features NEC/CEC standards alignment, UL certification for hazardous locations, and a NEMA rating set including 3R 4X 7 9. It is designed for Area classification Hazardous/Classified Locations, supporting safe operation in demanding environments and aiding regulatory approvals in the US and Canada.
The copper-free aluminum enclosure reduces corrosion and weight, easing installation and servicing. The clamped design simplifies field maintenance and part replacement, while high interrupt ratings and reliable UL/NEC/CEC compliance mitigate downtime and compliance risk. Over the equipment lifecycle, these factors translate to lower maintenance costs and improved total cost of ownership.
