TK30N500/5203 VTEKE Ultra high capacity window-type current transformer

The VTEKE TK30N500/5203 is a high-precision, window-type (hole-type) low-voltage current transformer engineered for high-capacity industrial power monitoring, main distribution switchboards, and energy management systems requiring exact precision. This industrial unit seamlessly transforms high primary alternating currents of up to 500A down to a standardized 5A secondary output, ensuring reliable data tracking when integrated with high-spec digital power analyzers, control relays, and energy meters.

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 during deployment.
