Primary Function: Designed to step down high alternating currents to a safe, measurable secondary current (typically 5A) so that digital meters, protective relays, or instrumentation can monitor heavy electrical loads.
Common Applications: Used in electrical control panels, power distribution systems, switchgear, and energy metering setups to track current usage safely.
Installation: The primary conductor passes through the central window aperture, while the secondary terminals (S1-K and S2-L) connect to measuring instruments or ammeters.
