Eaton Specification Sheet - EBMBB WT30EHD34
Feature → Business Impact → Application: The explosion-proof design with an EHD frame and three-pole configuration provides robust protection in hostile environments, reducing arc-flash exposure and equipment downtime, which is critical for oil, gas, chemical, and mining facilities. This translates to safer operation and lower maintenance costs on long-term projects where uptime matters. Application: Hazardous-location motor control and feeder protection in refineries and processing plants. Feature → Business Impact → Application: The 15A–100A amperage range and 100A frame size support scalable protection for a wide array of motors and load centers, enabling engineers to standardize on a single device family across multiple lineups. Application: Process lines and equipment with varying load profiles. Feature → Business Impact → Application: Copper-free aluminum enclosure delivers corrosion resistance and lighter handling in humid or corrosive environments, reducing repainting and replacement cycles. Application: Offshore platforms, chemical plants, and washdown areas. Feature → Business Impact → Application: Bolted/ground joint and gasketed cover construction enhances enclosure integrity against dust and water ingress, lowering field seal failures and maintenance visits. Application: Enclosures exposed to dust, moisture, and chemical vapors. Feature → Business Impact → Application: Comprehensive documentation and compatibility, including 3D models and installation sheets, speeds up engineering and assembly, shortening project timelines. Application: Panel builds and retrofit projects. Feature → Business Impact → Application: NEC/CEC compliance, area classifications, and multiple NEMA ratings (3, 3R, 4, 7, 9, 12) provide regulatory confidence and risk mitigation for safety-critical installations. Application: Regulatory-compliant power distribution in hazardous locations.
