Overview

The ABB QMS single-phase transformer, SKU 9T21B1003G02, is a 5 kVA unit designed for reliable power distribution. Manufactured in the USA, this transformer features an encapsulated copper core and coils for quiet operation and welded cores. It is housed in a NEMA 3R non-ventilated, weatherproof enclosure, providing protection against moisture and dust, suitable for outdoor installations. The unit is UL and cUL Listed. Installation is simplified with knockouts provided on the back and bottom for flexible conduit entry, and side-mounted holes offer easy access for maintenance. The integrated wiring compartment includes a ground stud for secure grounding. This transformer is suitable for applications requiring voltage transformation where durability and environmental resistance are critical, such as outdoor lighting and utility services. It operates at 60 Hz with dual voltage primary and secondary options. The insulation class is 185°C (NEMA) / 180°C (UL) with a 115°C Rise for units 200VA and above. Termination spacing is improved for greater flexibility with various UL listed connectors for copper or aluminum cable. This QMS series transformer is a dependable choice for general purpose applications. Specific catalog entries indicate NEMA 12/3R enclosures are available with pilot device knockout holes and space for control power transformers (e.g., ordering codes 1SQA012798R0001, 1SQA012855R0001, 1SQA012808R0001). Other NEMA 1 enclosures are also available (e.g., ordering codes 1SQA012777R0001, 1SQA012779R0001, 1SQA012780R0001). ABB also offers general purpose single-phase NEMA 3R transformers (e.g., 10B-24 series).
