VAYR Series Core Balance Current Transformer (CBCT)

ModelVAYR

Product overview

The VTEKE VAYR Series is a split-core rectangular Core Balance Current Transformer designed for residual current detection in existing low-voltage electrical installations. Its openable core enables installation around large conductors or busbars without dismantling the existing conductor arrangement, making it particularly suitable for retrofit earth leakage protection applications. When used with the VTEKE ELR-V3 Earth Leakage Relay, it provides the current signal required for earth leakage protection and monitoring.

Designed for use with the VTEKE ELR-V3 Earth Leakage Relay in retrofit applications where residual current detection is required around existing large conductors or busbars.
