FAQs
Install the EBMBA TT30TEB32 inside an approved explosionproof enclosure rated for hazardous locations, following UL/NEC guidelines. Use the bolted/ground joint/gasketed cover to seal, wire the three-pole device for 240 Vac/125–250 Vdc, and select the correct frame (100 A or 150 A) for your load. Proper grounding and torque per Eaton installation instructions are essential for safe operation.
Key specs include a 10–70 A amperage rating, three poles, 240 Vac/125–250 Vdc voltage range, and the TEB frame with copper-free aluminum. These details influence feeder sizing, short-circuit protection, and coordination with upstream devices. The option for 100 A or 150 A frame sizes supports scalable panel design and easier future expansion.
Yes. The EBMB series is designed for hazardous locations and offers UL hazardous-location approvals with NEC/CEC compliance, along with suitable NEMA ratings. It supports Class I/ Division 1 and Division 2 and Class II environments, making it appropriate for chemical processing, refineries, and other demanding process facilities.
Expect UL hazardous-location certification coverage, NEC/CEC compliance, and broad NEMA ratings (3, 3R, 4, 7, 9, 12). Area classification is clearly addressed, ensuring suitability for Hazardous/Classified locations. Documentation and UL certification pages are available through Eaton's resources for audit-ready compliance.
The copper-free aluminum enclosure, gasketed cover, and rugged construction reduce corrosion, ingress, and maintenance downtime. Reliable protection lowers unplanned trips, while compatibility with standard frames (100 A/150 A) simplifies installations and future upgrades. Overall, expect lower lifecycle costs and faster return on investment in facilities with harsh or classified environments.
