Eaton EBMBA TT70TED34 Explosionproof Circuit Breaker
Part Number: EBMBA TT70TED34
Quick Summary
The Eaton EBMBA TT70TED34 explosionproof circuit breaker protects electrical systems in hazardous locations across petrochemical, mining, and offshore facilities. A common pain point is finding protection devices that combine rugged construction with precise tripping characteristics for demanding loads in classified environments. This unit carries NEC/CEC compliance and NEC hazardous ratings across Class I, Division 1 and 2 as well as Class II and Class III, plus compatible NEMA ratings including 3, 3R, 4, 7, 9, and 12, ensuring regulatory alignment. Designed to work with bolted/ground joint/gasketed covers and a copper-free aluminum enclosure, it delivers reliable performance in tough installations. The result is reduced risk, easier procurement, and longer service life for critical feeders and motor circuits while supporting 480 Vac/250 Vdc operation and a 10–70 A range.

FAQs
Install the EBMB TT70TED34 with its bolted/ground joint/gasketed enclosure cover per NSE/IEC guidelines for Class I and II locations. Verify the enclosure rating matches the site classification, torque mounting hardware to manufacturer specifications, and connect conductors using approved conduit fittings. Use the three-pole arrangement for balanced protection and ensure proper alignment with the existing TED frame equipment.
Key specifications include a three-pole configuration with a 150A frame and an amperage range of 10 A through 70 A, rated for 480 Vac / 250 Vdc. The device uses the TED frame type and provides robust protection for hazardous locations, with a 70 A trip characteristic suitable for main feeders and motor circuits in demanding installations.
Yes. The EBMB series is designed for Hazardous/Classified Locations with NEC/CEC compliance and NEC hazardous ratings (Class I, Division 1 and 2; Class II Division 1 and 2; Class III), plus multiple NEMA ratings. Its copper-free aluminum enclosure and gasketed cover make it well-suited to chemical processing and offshore environments where ignition sources must be controlled and equipment reliability is paramount.
This breaker features NEC/CEC standards, NEC hazardous ratings across Class I, Division 1 and 2, Class II and Class III, and NEMA ratings 3, 3R, 4, 7, 9, 12. It is designed to meet global hazardous-location requirements, supporting safe operation, regulatory audits, and compliant integration with existing protection schemes.
The copper-free aluminum enclosure reduces corrosion risk and weight, aiding faster installation and easier field service. Its sealed, gasketed cover helps prevent ingress and maintain trip reliability, lowering maintenance cycles. The robust construction translates to longer service life, lower replacement costs, and predictable ROI for critical feeders and motor circuits in challenging environments.
