Overview

The Hammond Power Y075QTC is a 600V Class three-phase autotransformer designed for precise voltage correction in industrial distribution systems. Rated at 75 kVA, this unit efficiently steps down or steps up voltages between 480Y/400Y and 240Y/208Y, making it ideal for applications where load isolation from the supply line is not required. As an economical alternative to isolation transformers, it delivers reliable performance with less than 3% impedance, ensuring minimal voltage drop and energy loss. The Y075QTC features a heavy-duty Type 3R enclosure with standard side and rear conduit knock-outs, top-accessible high and low voltage leads, and optional Type 4/4X stainless steel enclosures for harsh environments. Certified to UL1604 (Class I, Division 2) and CSA standards, this autotransformer meets NEMA ST-20 sound level requirements and operates at a 130°C insulation system with an 80°C temperature rise. Encapsulated units are available for enhanced protection against moisture and contaminants. With a compact frame size and UL/CSA compliance, the Y075QTC is a dependable solution for voltage adjustment in manufacturing, commercial facilities, and renewable energy systems.
