Eaton EBMBB TT20TED34 Circuit Breaker - Explosionproof

Explosionproof construction and the TED frame deliver reliable fault interruption in hazardous environments, reducing arc flash risk and protecting critical loads. The 150A frame supports heavy feeders and motor circuits, while the three-pole design ensures balanced protection across phases in complex installations. Field engineers benefit from a familiar Eaton design language and coordinated safety documentation, helping to minimize commissioning time and avoid late-stage changes. With a 480 Vac/250 Vdc rating, this breaker covers both AC distribution and DC control circuits in demanding facilities. Enclosure features such as bolted/ground joint and gasketed cover maximize seal integrity and weather resistance in explosive atmospheres. Copper-free aluminum enclosure reduces weight, easing installation in retrofit projects and tight panel spaces while improving corrosion resistance in harsh environments. The rugged enclosure is designed for compatibility with standard EBMB accessories and installation practices, enabling quick integration into existing cabinets and production lines. Amperage range from 10 A through 150 A provides flexible protection for a broad spectrum of loads, from lighting feeders to small motors and pumps. Its three-pole configuration supports balanced fault protection and simplifies wiring in new builds or upgrades. The frame and enclosure are designed to fit standard control panels, minimizing custom fabrication and reducing overall installation cost. Compliance and certifications underpin global projects: Hazardous/Classified Locations area classification, NEC/CEC standards, and NEMA ratings including 3, 3R, 4, 7, 9, and 12. Canadian certification references via UL, and documentation packages such as installation sheets and catalogs simplify regulatory approvals. This mix of standards supports safe operation, audit readiness, and predictable maintenance across multinational sites.
