Overview

The Hammond Power Y075PKCN is a 75 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. The Y075PKCN features a 600Y-480Y VAC primary and secondary voltage rating, with an alternate rating of 480Y-380Y VAC, operating at 60 Hz. Built with a robust insulation system, it offers a 130°C rating with an 80°C rise as standard. The autotransformer incorporates a single winding design in a Wye configuration. It meets NEMA ST-20 standards for sound level and is UL Listed (File: E112313) and CSA Certified (File: LR3902). The enclosure is a heavy-duty type 3R, with optional type 4, 4X (Stainless steel), and 12 enclosures available. Terminations are front accessible with high and low voltage terminals suitable for copper cables. Standard side knock-outs are provided for conduit. Impedance is less than 3%. Manufactured in the USA, this autotransformer is ideal for adjusting supply voltage to match specific load requirements without the need for isolation.
