Overview

The ABB QB Single-Phase Encapsulated Transformer (SKU: 9T51B0011) is a dry-type, low-voltage transformer engineered for reliable indoor and outdoor power distribution in commercial and light industrial applications. This 1.5 kVA unit operates at 60 Hz with a fully encapsulated copper core and coils, providing superior protection against moisture, dust, and contaminants. The NEMA 3R non-ventilated enclosure ensures weatherproof performance for outdoor installations, while knockouts on the back and bottom simplify conduit connections. Side mounting holes enable secure wall or surface mounting, and the integrated wiring compartment includes a ground stud for safety compliance. This transformer supports dual-voltage primary and secondary configurations, allowing flexible step-up or step-down applications. The encapsulated design eliminates liquid cooling requirements, reducing maintenance and extending service life. With UL and cUL listings (XPTQ.E323774 and XPTQ7.E323774), it meets stringent safety and performance standards. Manufactured in an ISO 9001 certified facility, the QB series delivers consistent performance in control power, lighting, and general power distribution systems. Typical applications include machine tool control circuits, lighting systems, auxiliary power supplies, and small industrial or commercial installations where compact size and reliability are critical. The 1.5 kVA rating supports moderate loads, making it ideal for localized power distribution needs. Its design prioritizes durability and ease of installation, with features like pilot device knockout holes and space for control power transformers in compatible enclosures.
