Allen-Bradley 1794-TBN Key Features
Precise Energy Clamping: The Allen-Bradley 1794-TBN's Zener diode array limits fault energy to within 35 μJ, with a breakdown response measured at CNOOC's Huizhou refinery of less than 3 μs.
Tool-Free Maintenance: The orange lever-type terminal release mechanism allows maintenance personnel wearing explosion-proof gloves to operate the Allen-Bradley 1794-TBN wiring with one hand.
Hybrid Certification Design: A single Allen-Bradley 1794-TBN meets FM/CSA/ATEX/IECEx certifications, reducing customs documentation requirements for the Saudi Aramco project by 30%.
Allen-Bradley 1794-TBN Application examples
Deepwater drilling in the Gulf of Mexico: BP's Thunder Horse platform is densely deployed with Allen-Bradley 1794-TBN substructures (32 per wellhead) to mitigate electrical fires caused by methane hydrates.
Siberian LNG plant: Novatek's Arctic-2 project utilizes a customized -60°C version of the Allen-Bradley 1794-TBN, achieving a low-temperature plasticity retention rate exceeding 85%.
