The Instrument 460-480V Potential Transformer provides a 4:1 voltage step-down for instrument and metering circuits, with a 460–480 VAC primary and a secondary reflected by a 4:1 ratio. It is rated for 150 VA and lists a 0.6 W specification, indicating its burden characteristics for practical loads on the secondary. This device is designed for use in electrical panels and protection schemes where a safe, lower-voltage signal is needed for meters, relays, and instrumentation connected to high-voltage circuits.
