Industrial PT301 Potential Transformer 480:120

Amran PT301 Potential Transformer, 480:120 ratio (BIN631), is an instrument transformer used to scale down high-voltage signals for measurement and monitoring in industrial electrical systems. With a 480:120 (4:1) voltage ratio, the PT301 provides a secondary output of 120 V corresponding to the higher primary voltage, enabling safe connection to metering equipment and protection circuits. This model is part of Amran’s line of medium‑voltage potential transformers, designed to deliver a stable secondary signal for accurate voltage sensing in distribution and control applications. The BIN631 designation identifies the unit within field inventories and catalogs for easy reference in installation and maintenance records.
