General Electric 750X120181 Instrument Transformer

General Electric's 750X120181 Instrument Transformer provides a precise 1500:5 transformation ratio, meaning a high-current signal flowing through the primary is proportionally reduced to a 5 A secondary suitable for connection to measurement equipment and protective relays. Designed as an instrument transformer, it serves to supply metering devices, relays, and control circuits with a safe, scaled representation of the primary current, allowing accurate monitoring without exposing instrumentation to the full power circuit. With a 1500:5 ratio (300:1 overall), this GE component supports reliable current measurement in systems expecting a 5 A secondary, enabling compatibility with standard instrumentation and conventional protection schemes. The 750X120181 designation identifies a specific General Electric part intended for integration into electrical installations that require GE measurement and protection technology, emphasizing dependable signal conditioning and consistent performance in high-current environments.
