Overview

The Hammond Power Y300PKC is a 300 kVA, three-phase autotransformer designed for minor voltage adjustments in industrial distribution systems. This unit provides economical voltage correction as a cost-effective alternative to isolation transformers when electrical isolation is not required. The Y300PKC operates as either a step-up or step-down transformer, offering flexibility in power system configurations. Primary voltage options include 600Y or 480Y volts, with secondary outputs of 480Y or 380Y volts respectively. The transformer is rated for 60 Hz operation and features a robust three-coil, single 3-leg core construction with convection air cooling. It meets NEMA ST-20 sound level standards, with optional low-noise configurations available. Standard features include a heavy-duty Type 3R enclosure with front-accessible high and low voltage terminals for copper cable termination. Side knock-outs are provided for conduit entry (excluding stainless steel enclosures). Optional enclosure ratings include Type 4, 4X (stainless steel), and Type 12 for enhanced environmental protection.
