Eaton EBMBB TT15TED34 Circuit Breaker - Explosionproof
Part Number: EBMBB TT15TED34
Quick Summary
The Eaton EBMBB TT15TED34 circuit breaker protects hazardous-location power feeds in oil, gas, and chemical facilities. Many panels struggle with reliability and maintenance in explosive atmospheres, and this unit reduces risk through a rugged TED frame design and gasketed enclosure. It carries NEC/CEC compliance, UL hazardous-location certifications, and NEMA ratings 3, 3R, 4, 7, 9, 12, supporting global installations. With a 10 A through 150 A range and a three-pole configuration, it fits standard power-distribution layouts, while the bolted/ground joint and copper-free aluminum enclosure minimize corrosion and installation time. This translates to safer operation, lower downtime, and long-term lifecycle value for industrial automation projects.

Eaton Specification Sheet - EBMBB TT15TED34
Explosionproof EBMB design enhances safety by preventing ignition sources in hazardous environments, reducing risk for personnel and equipment. Business impact: lower incident rates and fewer unplanned outages in oil, gas, and chemical facilities. Application: ideal for control panels and power distribution in classified locations, including offshore platforms and chemical plants. The 10 A through 150 A range supports a wide load spectrum, enabling a single device to protect multiple motor and feeder circuits, improving panel density and reducing part counts. In field installations, the 150 A frame size, bolted/ground joint, and gasketed cover streamline mounting and sealing, minimizing commissioning time and maintenance. The copper-free aluminum enclosure reduces weight and corrosion potential, cutting lifecycle costs in harsh environments. Compatibility with standard TED frame breakers simplifies retrofit projects and spare-parts planning, delivering predictable maintenance cycles and continued regulatory compliance. Industry context: for certified hazardous-location protection, this breaker aligns with NEC/CEC requirements and UL listings while meeting demanding NEMA ratings 3, 3R, 4, 7, 9, 12.

FAQs
Installers should plan for a gasketed, bolted/ground joint enclosure to maintain integrity in classified areas. Ensure the enclosure is properly grounded and that wiring entries accommodate the 14.78 in length, 26.9 in height, and 10.25 in width. Position the device to allow heat dissipation and follow NEC/CEC requirements for hazardous-classified locations. Use copper-free aluminum components to minimize corrosion and weight during routing and mounting in tight spaces.
Yes. The EBMBB TT15TED34 is rated for 480 VAC / 250 VDC and comes in a three-pole configuration with a 150A frame size. The unit supports a 10 A through 150 A amperage range, enabling scalable protection across multiple motor and feeder circuits. Its TED frame type standardizes installation with other EBMB models, simplifying cross-compatibility in complex panels.
This breaker supports NEC/CEC compliance and UL hazardous-location certifications, with area classification for Hazardous/Classified Locations. It also aligns with NEMA ratings including 3, 3R, 4, 7, 9, 12, enabling safe operation across a broad range of environmental conditions and international installations.
The enclosure uses a bolted/ground joint with a gasketed cover, delivering a robust seal against dust, moisture, and gas ingress in hazardous environments. The copper-free aluminum construction reduces weight and corrosion risk, making field servicing easier and safer while preserving enclosure integrity during routine maintenance, inspections, and retrofits.
Although initial cost may be higher than standard breakers, the EBMBB TT15TED34 delivers lower maintenance downtime, reduced risk of hazardous-location incidents, and longer service life due to corrosion-resistant copper-free aluminum. Its broad NEC/CEC and UL hazard certifications support faster approvals and fewer compliance delays on global projects, improving overall project ROI and lifecycle cost of ownership.
