FAQs
This explosionproof three‑pole breaker is designed for hazardous locations (Class I/Division 1 & 2; Class II/III) and supports demanding environments found in chemical plants, refineries, and mining sites. The copper‑free aluminum enclosure and gasketed cover provide robust protection against dust, moisture, and corrosive atmospheres, simplifying field deployment in rugged settings.
The EBMB TT25TED34 uses a 150A frame with a 10–150 A adjustable amperage range. It operates at 480 Vac or 250 Vdc and is a three‑pole device within the TED frame family, suitable for motor feeders and distribution panels in demanding environments.
The TED frame provides coordinated protection across three phases, improving fault isolation and protection coordination. In hazardous locations, this reduces miscoordination risk, supports faster fault clearance, and enhances overall system safety when paired with compatible controls and protective relays.
The EBMB TT25TED34 carries NEC/CEC approvals for hazardous locations (Class I, Division 1 & 2; Class II/III) and supports multiple NEMA ratings (3, 3R, 4, 7, 9, 12). It is designed for compliance with rigorous industrial protection requirements and UL documentation.
Leverage the gasketed enclosure and bolted joints to minimize ingress risks, reducing maintenance cycles in harsh environments. Access to installation instructions and 3D design files accelerates commissioning, lowers design risk, and supports ROI through faster project delivery and fewer field changes.
