VST-ELR Serisi Toplama Toroidal Kaçak Akım Transformatörü (CBCT)

The VTEKE VST-ELR Series is a Summation Current Transformer designed for use with Earth Leakage Relays (ELR) in low-voltage electrical installations. It sums the secondary currents received from multiple current transformers and provides the resulting residual-current signal to the earth leakage relay, enabling multiple circuits to be monitored through a single relay.

Designed for earth leakage protection systems where residual current from multiple circuits is monitored through a single Earth Leakage Relay.
