Eaton Specification Sheet - EBMBA TT40TEB32
Three-pole design with a 240 Vac/125-250 Vdc rating and the TEB frame provides synchronized protection for three-phase loads, improving system reliability and limiting equipment damage in hazardous environments. This translates to reduced unplanned outages and lower maintenance costs in process plants and facilities with strict safety standards. The copper-free aluminum enclosure, together with a bolted/ground joint and gasketed cover, delivers corrosion resistance and a robust seal that simplifies field installation and service in challenging locations, while keeping weight manageable for installation crews. The 100 A or 150 A frame size supports higher-current circuits without needing additional gear, enabling a leaner panel design and fewer alternative SKUs. With a three-pole configuration plus a 10 A through 70 A amperage range, engineers gain flexible protection for varied motor loads, feeders, and control circuits. Certifications including NEC/CEC and hazardous-location ratings provide immediate regulatory alignment, helping you pass audits and maintain safety baselines. Designed for EN/IEC-adjacent industrial ecosystems, the EBMB TT40TEB32 integrates smoothly with existing EBMB families, bolstering compatibility with bolted covers and gasketed enclosures while reducing rework during retrofits.

FAQs
The EBMB TT40TEB32 uses a three-pole frame with a copper-free aluminum enclosure and supports bolted/ground joint configurations with a gasketed cover. This combination is designed for hazardous/classified locations and aligns with EN/IEC-adjacent industrial standards, facilitating straightforward retrofit into existing EBMB installations and simplified field maintenance.
Key specs include a 240 Vac/125-250 Vdc voltage rating, a 10 A through 70 A amperage range, and a 100 A or 150 A frame size for the TT40TEB32. It is a three-pole device with a TEB frame type, intended for 3-phase protection in demanding environments.
Yes. The EBMB TT40TEB32 is rated for Class I Division 1 and Class I Division 2, Class II Division 1 and 2, and Class III hazardous locations. It also carries NEC/CEC standards, NEMA ratings (3, 3R, 4, 7, 9, 12), and is designed for areas classified as Hazardous/Classified Locations, ensuring regulatory compliance in industrial facilities.
The 100 A or 150 A frame size supports larger feeder and motor protections within a compact footprint, enabling a leaner panel design and reducing the need for multiple components. This simplifies wiring, lowers enclosure space requirements, and can shorten commissioning time while meeting higher current protection needs in hazardous environments.
Leverage the gasketed, gasketed-cover enclosure with bolted/ground joint design to minimize ingress risk and simplify seal checks during preventive maintenance. The copper-free aluminum construction improves corrosion resistance, reducing service frequency in challenging environments. Use the standard EBMB installation sheets and kits for gasket replacement (IF1616 series) to minimize downtime during routine gasket maintenance and ensure ongoing compliance with hazardous-location standards.
