TK30N300/5203 VTEKE Ultra high capacity window-type current transformer

The VTEKE TK30N300/5203 is a high-precision, window-type (hole-type) low-voltage current transformer engineered for critical industrial power monitoring, sub-metering, and energy management systems where premium accuracy is paramount. This unit efficiently steps down high primary alternating currents of up to 300A to a standardized 5A secondary output, ensuring a seamless interface with digital power analyzers, control relays, and high-spec ammeters.

Featuring an open octagonal inner window chamber, this current transformer mounts directly over active lines. This configuration permits straightforward installation without needing to split copper bars or cut cables, drastically lowering labor costs and panel downtime.
