Overview

The ABB 9T33 Single-Phase Low-Voltage Dry-Type Transformer (SKU: 9T33C2670) is engineered for balanced 3-wire 120/240V secondary voltage systems, delivering high efficiency and compliance with global standards. Certified under NRCan (C802.2) and DOE (10 CFR 431, Subpart K) for energy efficiency, this transformer ensures reduced operational costs and environmental impact. It holds UL and cUL listings to UL 1561 and CSA C22.2 No.47, meeting rigorous safety and performance benchmarks. The core and coil assembly is constructed from grain-oriented, annealed silicon steel, optimizing magnetic performance and longevity. Core and coil assemblies are mounted on neoprene isolation pads to minimize vibration and noise, enhancing operational reliability. Installation and maintenance are streamlined with outward-facing feet, a single-piece front/back panel, and integrated lifting eyes on the top core clamp for safe handling. Most units up to 150 kVA include a lug kit and copper ground bar kit for simplified wiring. Optional IR viewing windows enable non-invasive thermal inspections on select models, reducing downtime. Qualified to seismic requirements per IEEE-693-2005, IBC-2021, and CBC 2022, the 9T33 is ideal for seismically active regions. This transformer is manufactured in the US and is UL Energy Verified, making it a trusted choice for data centers, healthcare facilities, manufacturing plants, and institutional applications where reliability and compliance are critical.
