Overview

ABB’s QMS single-phase transformer (SKU: 9T21B9106) is a NEMA 3R-rated, nonventilated weatherproof unit designed for reliable outdoor power distribution. The encapsulated core and coil construction prevents moisture ingress, ensuring long-term performance in wet or humid environments. The NEMA 3R enclosure provides superior protection against dust, rain, and corrosion, meeting stringent safety and durability standards for industrial and commercial applications. Key features include knockouts on the back and bottom for flexible cable entry, side-mounted mounting holes for simplified installation and maintenance, and an integrated wiring compartment with a ground stud for secure grounding. Pilot device knockout holes are included for control power transformer integration, and the enclosure is rated for NEMA 12/3R environments, making it suitable for both indoor and outdoor use. Manufactured in the USA by ABB - Electrification, the QMS series supports single-phase power requirements with consistent, high-quality output. Typical applications include lighting systems, HVAC units, control panels, and utility distribution. The transformer’s design ensures dependable performance in commercial, industrial, and utility settings, combining durability with ease of installation for cost-effective outdoor electrical distribution. Ordering flexibility is enhanced with multiple NEMA-rated enclosures available, including NEMA 12/3R and NEMA 1 configurations, depending on specific application needs. The inclusion of pilot device knockout holes and space for control power transformers further expands its utility in complex electrical systems.
