Overview

The ABB Type QL Low-Noise General Purpose Dry-Type Transformer (SKU: 9T10A1007G62) delivers quiet, efficient power for noise-sensitive environments. Rated at 225 kVA, this transformer converts 480V Delta primary power to 208Y/120V secondary power, ideal for commercial and industrial applications requiring stable, low-voltage distribution. Engineered to DOE 2016 efficiency standards and UL Energy Verified, it ensures energy savings without compromising performance. Key features include noise reduction levels of -3dB or -5dB below NEMA ST-20 standards, achieved through core and coil assemblies mounted on rubber isolation pads to dampen vibrations. The transformer is available with aluminum windings (as specified for this SKU) and supports all three temperature rise ratings (80°C, 115°C, and 150°C), with the 150°C rise option selected here. Its dry-type construction eliminates oil, making it safe for indoor installations and compliant with environmental regulations. Designed for reliability, the Type QL transformer meets seismic requirements per IEEE-693-2005, IBC-2021, and CBC 2022, ensuring structural integrity in earthquake-prone regions. The single-piece front/back panel simplifies installation and service, while the NEMA 2 enclosure provides protection against environmental contaminants. With a 3.8% impedance and K-factor of K1, it supports harmonic loads effectively. Built in the USA, this transformer combines durability, efficiency, and quiet operation for critical applications such as data centers, hospitals, schools, and office buildings.
