The INSTRUMENT 140-402 is an instrument current transformer that steps down high line currents to a 5 A secondary with a 4000:5 A ratio, enabling accurate metering and protective relays in electrical systems. It is specified for 50/60 Hz operation and is rated for up to 600 V, making it compatible with common industrial power distributions and control panels. Typical applications include feeding meters, relays, and panel instrumentation in switchgear and control systems where precise current measurement is essential for monitoring and protection.
