Overview

ABB's QB single-phase transformers, SKU 9T51B0072, are designed for general-purpose industrial applications requiring reliable voltage transformation. These units feature a fully encapsulated core and coils, providing robust protection against moisture, dust, and contaminants for enhanced durability in harsh environments. The transformer is housed in a NEMA 3R non-ventilated, weatherproof enclosure, making it suitable for outdoor or exposed installations where environmental resistance is critical. The enclosure is designed with pilot device knockout holes and includes space for a control power transformer, allowing for flexible installation configurations to meet specific application needs. Knockouts are strategically positioned on both the back and bottom of the unit, while side mounting holes facilitate easy access and maintenance. The integrated wiring compartment is equipped with a ground stud to ensure secure and reliable electrical connections. Manufactured in the USA by ABB Electrification, these transformers meet stringent industry standards, including UL and CSA certifications, ensuring compliance with safety and performance requirements. The QB series is engineered for power distribution needs in a wide range of industrial and commercial settings, providing dependable single-phase voltage conversion for applications such as lighting, control systems, and auxiliary power supplies. Specific electrical and physical specifications, including input/output voltage ratings, kVA capacity, dimensions, and weight, should be referenced from the official ABB QB series catalog data for precise application planning. The NEMA 12/3R enclosure options offer versatility for different environmental protection levels, with specific models like ENCX2W117C6 and ENCX1W114C2 featuring pilot device knockouts and control power transformer space.
