Overview

ABB's QB single-phase encapsulated transformers (SKU: 9T51B0157) are designed for reliable power distribution in demanding indoor and outdoor environments. Manufactured in the USA, these transformers feature a robust NEMA 3R non-ventilated, weatherproof enclosure, providing essential protection against falling rain, sleet, and external ice formation. The core and coils are fully encapsulated, ensuring enhanced durability and safety. Designed for flexibility, the QB transformers offer convenient knockouts on the back and bottom for easy conduit entry, and side-mounted holes facilitate straightforward installation and maintenance. The integrated wiring compartment includes a ground stud for secure electrical connections. Available in a range of kVA ratings from 0.05 to 3 kVA, and supporting dual voltage primaries and secondaries for versatile buck-boost applications, these units are UL and cUL Listed (XPTQ.E323774 and XPTQ7.E323774). The non-ventilated design eliminates the need for cooling fans, reducing maintenance requirements and operational costs. Ideal for general lighting, power service, control panels, and distribution networks in commercial, industrial, and utility sectors. Termination spacing is improved for greater flexibility with various UL listed connectors for copper or aluminum cable. Specific models like ENCX2W117C6 and ENCX1W114C2 offer NEMA 12/3R enclosures with pilot device knockout holes and space for control power transformers, while ENCX2W113C5 and ENCX2W114C1 feature NEMA 1 enclosures with similar knockout and space provisions. Other variants, such as ENCX2W117C5, ENCX2W115C2, ENCX2W114C2, provide NEMA 1 or NEMA 12/3R enclosures with specific knockout and space configurations.
