Eaton Specification Sheet - EBMBB WT80EHD34
Explosionproof EBMB design with a 100A frame and three poles delivers robust protection against overload and short circuits in hazardous locations. This reliability reduces the risk of ignition and unplanned downtime, meeting stringent safety and regulatory expectations. It is well suited for oil and gas platforms, chemical processing plants, and mining operations where enclosure integrity is non negotiable. Copper-free aluminum enclosure coupled with bolted/ground joint/gasketed covers offers corrosion resistance and durable sealing in dusty, humid, or chemically aggressive environments. The business impact is lower maintenance costs and fewer field failures, translating to reduced maintenance cycles and faster repair times. This configuration is ideal for outdoor installations and harsh indoor environments in refineries or wastewater facilities. Wide amperage range from 15A through 100A, 480Vac/250Vdc rating, and an EHD frame size support seamless integration with existing feeders and distribution panels, simplifying procurement and reducing part substitutions during upgrades. This is particularly valuable for mid-size plants and modular expansions where consistent protection matters. NEC/CEC compliance and a broad spectrum of NEMA ratings (3, 3R, 4, 7, 9, 12) provide installation flexibility across indoor, outdoor, and hazardous-area applications. The payoff is faster regulatory approvals, safer documentation, and a lower total cost of ownership over the life of the installation. Enclosure compatibility and installation readiness are enhanced by provided documentation and CAD resources in the downloads, including catalog pages, 3D models, and installation sheets, which reduces engineering effort and accelerates project timelines while ensuring correct fit and wiring practices.

FAQs
Begin by reviewing the installation instructions and wiring diagrams from Eaton, ensuring the enclosure is rated for the intended hazard location. Mount the three-pole breaker securely on a compatible bus, connect earth/ground, and use the gasketed, bolted cover to maintain enclosure integrity. Verify 480 Vac/250 Vdc ratings and 15–100A ampacity match the feeder design, then perform final inspection for compliance with NEC/CEC requirements.
The unit is designed as explosionproof with an EHD frame for robust protection in Class I/II/III locations. It carries NEC/CEC compliance and hazardous-location classifications, plus a NEMA-rated enclosure set (3, 3R, 4, 7, 9, 12). Its copper-free aluminum enclosure and gasketed construction resist corrosion and ingress, delivering reliable protection in demanding environments like refineries and offshore facilities.
The EBMB WT80EHD34 is a three-pole breaker with a 100A frame size and amperage range from 15A to 100A. It operates at 480 Vac or 250 Vdc, and is designed for three-pole protection in industrial power distribution circuits, offering reliable overload and short-circuit protection for demanding motor feeders.
Yes. It adheres to NEC/CEC standards and is rated for hazardous-location service with Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III approvals. It also supports corresponding NEMA ratings (3, 3R, 4, 7, 9, 12) to fit a wide range of installation types, from indoor panels to outdoor enclosures.
The copper-free aluminum enclosure reduces corrosion-related maintenance, while the explosionproof construction lowers ignition risk and downtime in hazardous locations. With broad compatibility and long service life, the unit minimizes spare parts inventory and field failures, delivering lower total cost of ownership and improved uptime for critical feeders and motors.
