Schneider Electric 460R-240 Voltage Transformer

Schneider Electric’s Square D 460R-240 Voltage Transformer is a 240 V primary to 120 V secondary instrument transformer (model 460R-240) in the 460R family, delivering a 2:1 voltage ratio for measurement and indication tasks. It is designed for voltage indication with lower accuracy and small burden, making it suitable for use with voltmeters, transducers, and other electrical indicating and recording instrumentation that monitor system voltage. The device carries Class 4210 accuracy and supports line-to-line or line-to-ground connections on the primary voltage as indicated, providing a safe, scaled signal for sensing circuits in three-phase or single-phase panels. The 460R-240 variant specifies a 240 VAC primary and 120 VAC secondary, aligning with standard 120 V instrumentation inputs without altering control logic or signaling. Thermal rating is 150 VA at 30 °C (100 VA at 55 °C), with a burden of about 0.6 W, reflecting its role as a low-burden measurement transformer rather than a high-power distribution device. Typical applications include panel metering, energy monitoring, and feeding voltage inputs to data acquisition or protective or recording equipment in industrial control environments. As part of Schneider Electric’s instrument-transformer lineup, the 460R series is explicitly designed for voltage indication, offering a reliable, general-purpose solution for stepping down higher voltages to 120 V for instrumentation.
