Eaton Specification Sheet - EBMBG WT150JDB36
Explosionproof, hazardous-location ready design provides NEC/CEC compliance and Class I/II rating, reducing safety risk and regulatory exposure while enabling installation in oil, gas, and chemical processing facilities. This translates to measurable uptime improvements and lower risk of costly outages in demanding environments. The JDB frame and 250A maximum capacity support versatile feeder protection for large circuits, while the 70–250 A amperage range covers a wide portion of typical plant loads, simplifying parts stocking and future expansion. The three-pole configuration offers balanced protection for phase systems, and 600 Vac compatibility aligns with common plant distribution schemes, streamlining procurement and maintenance planning. Copper-free aluminum enclosure enhances corrosion resistance and weight considerations in harsh locations, improving lifecycle performance and total cost of ownership. Bolted/ground joint/gasketed enclosure construction further guards against ingress, reducing maintenance cycles and service calls. Installation is facilitated by compatibility with EBMB enclosures, enabling straightforward retrofits and modular upgrades in existing switchgear layouts. Certification and accessible documentation—from UL certifications to SP3D models and catalogs—support faster audit readiness and commissioning, helping teams stay compliant while accelerating project timelines. With its robust build and industry-aligned specs, the EBMBG WT150JDB36 is well-suited for hazardous-location power distribution in mining, refining, and chemical processing applications, where reliability and safety are non-negotiable.
