FAQs
Install the EBMB TT50TED34 using the bolted/ground joint/gasketed enclosure to ensure a tight seal in hazardous environments. Adhere to installation sheets such as IF1150 and SP3D design packages for proper clearance, torque, and wiring practices. Ensure the three-pole arrangement aligns with your control panel and motor starter configuration to optimize protection coordination.
Verify the 150A frame size, 10 A through 70 A amperage rating, and the voltage rating of 480 Vac / 250 Vdc. Confirm the TED frame type and three-pole construction, along with copper-free aluminum enclosure suitability for your environment. Ensure compatibility with your distribution panels and downstream devices to avoid cross-trip issues.
Yes. The EBMB series provides NEC hazardous ratings including Class I Division 1 and 2, Class II Division 1 and 2, and Class III, along with area classifications for hazardous/classified locations. It also carries UL certification for explosionproof applications, supporting safe operation in demanding industries like oil & gas, chemicals, and mining.
The EBMB TT50TED34 supports NEC/CEC standards, UL hazard-location certification, and NEMA ratings including 3, 3R, 4, 7, 9, 12. These certifications help confirm suitability for hazardous locations and varied environmental conditions, reducing compliance risk during audits and commissioning.
Expect improved reliability due to rugged copper-free aluminum construction and a sealed enclosure, which reduces corrosion-related downtime. The wide amperage range and 150A frame simplify spare-part management, while certified compliance minimizes rework and inspection costs, delivering faster project timelines and longer service intervals in demanding facilities.
