FAQs
For hazardous locations, ensure proper enclosure sealing and gasket integrity, use copper-free aluminum housing for corrosion resistance, and follow NEC/CEC wiring methods. The KD frame requires compatible mounting and bolted/ground joint connections; verify area classification and required approvals before commissioning.
Key specs include a 600 Vac/250 Vdc rating, KD frame, 3-pole configuration, and 100–400 A adjustable range. These determine how the breaker protects feeders and motors, allowances for fault current, and compatibility with existing switchgear while maintaining compliance in hazardous locations.
Yes. The EBMBK WT150KD36 is designed for Hazardous/Classified Locations with NEC/CEC compliance and area classifications. Its explosionproof construction, corrosion-resistant enclosure, and three-pole protection make it well-suited for chemical processing, refining, and other high-risk environments.
This unit complies with NEC/CEC standards and is rated for Hazardous/Classified Locations. It supports NEMA ratings 3, 3R, 4, 7, 9, and 12, reflecting durability across indoor and outdoor hazardous environments, with Canadian certifications available through UL references.
Expect reduced maintenance due to a sealed, gasketed enclosure and corrosion-resistant aluminum construction. ROI benefits arise from improved uptime, fewer workspace interruptions in hazardous areas, and easier installation with a standardized KD frame, reducing labor and spare parts costs over the lifecycle.
