Overview

ABB's QB single-phase transformers (SKU: 9T51B0093) are designed for general purpose applications requiring reliable voltage transformation. These units feature an encapsulated core and coils, providing robust protection against environmental factors and physical damage. The transformer is housed in a non-ventilated NEMA 3R weatherproof enclosure, ensuring dependable performance in outdoor installations. The enclosure is constructed from heavy-gauge steel with a durable powder-coated finish for corrosion resistance. Knockout holes are provided on both the back and bottom of the enclosure for flexible conduit entry and wiring management, with additional knockouts on the sides for added installation versatility. Side-mounted holes offer easy access for secure installation, while the internal wiring compartment includes a ground stud for safe and compliant electrical connections. The QB series is manufactured in the USA and adheres to stringent quality standards, including UL and CSA certifications. This specific model, 9T51B0093, is part of the general-purpose single-phase NEMA 3R offering within the QB line, designed for indoor or outdoor use in applications such as lighting, HVAC, and industrial control systems. The encapsulated design eliminates the need for liquid insulation, reducing maintenance requirements and environmental concerns. The NEMA 3R rating ensures protection against falling rain, sleet, and external ice formation, making it suitable for harsh outdoor conditions. The transformer operates at a maximum ambient temperature of 40°C and is available in various primary and secondary voltage configurations to meet specific application needs.
