Overview

The Hammond Power Y300QTC is a 300 kVA, three-phase autotransformer designed for applications requiring minor voltage adjustments in distribution systems. This unit serves as an economical alternative to isolation transformers when load isolation is not a primary concern. It efficiently functions as either a step-up or step-down transformer, offering flexibility for various electrical configurations. Key specifications include a 600Y primary voltage and selectable secondary voltages of 480Y, 240Y, or 208Y. Built with a robust insulation system, it features 130°C insulation with an 80°C rise as standard, ensuring reliable operation. The autotransformer is UL Listed (File: E112313) and CSA Certified, meeting stringent industry standards. Its heavy-duty Type 3R enclosure provides protection in demanding environments, with optional Type 4, 4X, and 12 enclosures available. Terminations are top accessible, featuring separate high and low voltage lead wires or copper tabs for straightforward connections. Standard side and rear conduit knock-outs facilitate installation. The impedance is less than 3%, and sound levels meet NEMA ST-20 standards, with optional low-noise configurations available. Manufactured in the USA, the Y300QTC is engineered for performance and longevity in industrial settings.
