Overview

ABB QB single-phase transformers (SKU: 9T51B0032) are general-purpose encapsulated units designed for reliable power distribution in industrial and outdoor environments. These transformers feature a fully encapsulated core and coils, providing superior protection against moisture, dust, and corrosive elements. Housed in a NEMA 3R non-ventilated, weatherproof enclosure, they meet stringent environmental durability requirements for outdoor installations or harsh industrial settings. Key features include knockouts on the back and bottom for flexible conduit entry, side-mounted mounting holes for simplified installation and maintenance, and a dedicated wiring compartment with a ground stud for secure electrical connections. The encapsulated design eliminates the need for liquid insulation, reducing maintenance and environmental risks while ensuring consistent performance. Available enclosure options include NEMA 12/3R and NEMA 1 variants, each tailored for specific applications. NEMA 12/3R enclosures (e.g., 1SQA012798R0001, 1SQA012855R0001) include pilot device knockout holes and space for control power transformers, while others (e.g., 1SQA012784R0001) omit these features for streamlined configurations. NEMA 1 enclosures (e.g., 1SQA012777R0001, 1SQA012779R0001) also offer pilot device knockout holes and variable space for control power transformers, depending on the model. Manufactured in the USA, ABB QB transformers are ideal for general-purpose single-phase applications, including lighting, HVAC systems, and machinery control circuits. Their compact, durable design ensures long-term reliability in commercial buildings, industrial facilities, and outdoor installations where environmental protection and ease of installation are critical.
