Eaton EBMBK WT300KD36 Circuit Breaker - Hazardous Locations
Part Number: EBMBK WT300KD36
Quick Summary
The Eaton EBMBK WT300KD36 circuit breaker protects hazardous-location electrical panels in industrial facilities. Engineers often struggle to balance safe circuit protection with minimal downtime in harsh environments. This unit carries NEC/CEC compliance and Hazardous/Classified Locations ratings, including Class I, Division 1 (and related classifications), plus compatible NEMA enclosures for rugged service. With a copper-free aluminum enclosure and a KD frame, it delivers durable protection while simplifying installation and reducing lifecycle costs for panel builders and integrators. Designed for 600 Vac/250 Vdc operation in a three-pole configuration, it aligns with modern electrical protection strategies for multi-location facilities. Its 400 A frame size options and bolted/ground joint/gasketed cover design support flexible installation in standard steel or fiberglass enclosures.
