Allen-Bradley 7SHT-501 is a 500:5 A current transformer designed as an instrument transformer for current sensing in electrical power systems. It operates at 50–400 Hz, with a maximum voltage rating of 600 V, and provides a 5 A secondary from a 500 A primary (100:1 turns ratio). This CT is intended for metering and instrumentation use where a standard 5 A secondary is required from a high-current primary.
