FAQs
When deploying the EBMBA TT20TEB32, ensure the enclosure is rated for Hazardous/Classified Locations and use the bolted/ground joint/gasketed cover construction to maintain integrity. Mounting should follow the TE B frame compatibility and align with NEC/CEC requirements. Verify a three-pole installation for balanced phase protection and confirm 240 Vac/125-250 Vdc supply compatibility with panel assemblies in classified spaces.
Key specs include a 240 Vac/125-250 Vdc voltage rating, a 10–70 A adjustable amperage range, and three poles in a TEB frame. The unit supports 100 A or 150 A frame sizes, with a 20 A trip setting typical for the model family, and is designed for use in industrial control panels subject to hazardous-location standards.
Yes. The EBMB series is rated for Hazardous/Classified Locations, with NEC classifications including Class I, Division 1 and 2, Class II, and Class III. It also meets NEC/CEC standards and aligns with applicable NEMA ratings, streamlining regulatory approvals for oil & gas, chemical, and mining applications.
The EBMB series provides explosionproof protection, a copper-free aluminum enclosure for lighter installations, and bolted/ground joint/gasketed covers to maintain enclosure integrity.
