Janitza KUW1/30-100 trasformatore di corrente split-core 100/1 A, apertura 18 mm, 1,5 VA, classe 1 1503512

Measuring high currents safely requires a transformer that can be installed without interrupting the circuit. The Janitza KUW1/30-100 split-core current transformer solves this by clamping around an existing cable, converting a 100 A primary current into a standard 1 A secondary signal for meters and relays.

Who is it for

Electricians and panel builders who need to retrofit energy monitoring or protection on existing installations. Its split-core design allows installation on live conductors without disconnection, reducing downtime and risk.
