Overview

ABB’s QMS single-phase transformer (SKU: 9T21B9143) delivers reliable power conversion with encapsulated core and coil technology in a NEMA 3R non-ventilated weatherproof enclosure. Designed for outdoor and harsh environment applications, this transformer resists dust, rain, and corrosion, ensuring long-term durability. The encapsulated design eliminates moisture ingress and enhances insulation performance, making it ideal for utility, commercial, and industrial installations where reliability is critical. Key features include knockouts on the back and bottom for flexible conduit entry, while side-mounted holes simplify installation and maintenance access. The integrated wiring compartment features a ground stud for secure grounding, streamlining electrical connections and compliance with safety standards. Built in the USA, this transformer combines ABB’s engineering excellence with robust construction to meet demanding operational requirements. Suitable for single-phase power distribution in outdoor enclosures, these transformers support applications ranging from lighting and control circuits to small power loads. Their compact design and weatherproof rating make them a preferred choice for facilities requiring dependable performance in variable environmental conditions. The NEMA 3R enclosure ensures protection against falling dirt, rain, sleet, and snow, while the non-ventilated design prevents internal condensation and contamination. Additional versatility comes from pilot device knockout holes for control wiring flexibility and space in the enclosure for a control power transformer, enhancing adaptability in complex installations. The encapsulated core and coils provide superior insulation and thermal performance, reducing the risk of failure in high-stress environments. With a focus on durability and ease of installation, the QMS series is engineered to deliver consistent performance in outdoor and industrial settings.
