Eaton EBMBA WT50FDB36 Explosionproof - Hazardous Locations
Part Number: EBMBA WT50FDB36
Quick Summary
EBMBA WT50FDB36 is an Eaton explosionproof circuit breaker designed for hazardous-location motor control and power distribution. In challenging environments, maintenance and compliance can quickly escalate costs and downtime, making robust protection essential. This model delivers NEC/CEC compliance with hazardous-location ratings (Class I, Division 1 and 2; Class II/III) and a versatile NEMA footprint to fit common enclosures. The copper-free aluminum enclosure, bolted/ground joint/gasketed cover, and three-pole construction simplify installation while improving sealing against dust, moisture, and arcing. With a 600 Vac rating and a 150A frame, it supports a 10 to 70 A range for diverse circuits, enabling safer, scalable protection without multiple device types.
