Overview

ABB's Totally Enclosed Non-Ventilated (TENV) transformer, SKU 9T85B3872, is a UL Listed dry-type transformer designed for environments where standard open-ventilated units are unsuitable due to atmospheric contaminants. This transformer is engineered to operate safely in the presence of dust, dirt, lint, or moisture, including applications subject to sprays or controlled wash-down procedures. It is UL Listed through 75kVA for indoor or protected outdoor installations and meets NEMA TP-1 efficiency standards, ensuring energy savings without sacrificing performance. The 9T85B3872 features a 105°C insulation system and a 55°C temperature rise, providing reliable operation in challenging industrial settings. It includes primary and secondary fusing for circuit protection, with two primary fuses, one secondary fuse, and associated holders/clips. The transformer is manufactured in the US and is CSA certified, making it a compliant choice for North American applications. Key specifications across the TENV series include: - Insulation systems ranging from 105°C to 180°C (e.g., T6350PS1, T6100PS1, T6200PS1, T6075PS1, T6150PS1, T6250PS1, T6045SF, T4050PSF1 at 105°C; TC4300F1 at 130°C; T63K1 at 180°C). - Temperature rises of 55°C (standard), 80°C (TC4300F1), or 120°C (T63K1). - Primary fusing configurations vary by model: two primary fuses with holders (e.g., T6350PS1, T6100PS1) or single primary fuse (e.g., T6045SF). - Secondary fusing included in most models (e.g., one secondary fuse with clips in T6350PS1). - UL and CSA certifications for broad market acceptance. Applications include manufacturing plants, food processing facilities, textile mills, and other industrial environments where transformer contamination or moisture exposure is a concern. The TENV design eliminates the need for ventilation openings, reducing the risk of particulate ingress while maintaining compliance with safety and efficiency standards.
