Overview

ABB's QB series single-phase transformers (SKU: 9T51B0511) offer reliable power conversion for industrial applications, suitable for both indoor and outdoor use. These transformers feature a fully encapsulated copper core and coils, providing robust protection against moisture, dust, and contaminants. The NEMA 3R non-ventilated enclosure ensures durability and weather resistance. Designed for general-purpose use, the QB series supports a range of input and output voltages and is rated from 0.05 kVA up to 3 kVA. The non-ventilated design contributes to quiet operation and meets UL-5085 and NEMA ST20 standards. Installation is facilitated by knockouts provided on the back and bottom for flexible conduit entry, and side-mounted holes offer easy access for mounting. The integrated wiring compartment includes a ground stud for secure grounding and offers ample space for UL-listed connectors, accommodating both copper and aluminum cables. These transformers are ideal for applications such as general lighting, power distribution, and control circuits in commercial buildings, manufacturing facilities, and utility environments where environmental exposure is a concern. The QB series is UL and cUL listed. Specific enclosure types within the QB series can include NEMA 12/3R or NEMA 1, with options for pilot device knockout holes and space for control power transformers, depending on the specific model configuration (e.g., ENCX2W117C6, ENCX1W114C2, ENCX2W113C5, ENCX2W114C1, ENCX2W115C2, ENCX2W117C5, ENCX2W114C2).
