CNC Electric YC6VA 2-Pole Adjustable Voltage & Current Protection Relay

Product Identification

Important: YC6VA is a voltage/current monitoring protection relay. The official documents specify a 1NO relay output but do not give it the short-circuit interrupting function of an MCB or the earth-leakage function of an RCCB/RCBO. Use suitable upstream protection selected by a qualified electrician.

Product Title

CNC Electric YC6VA 2-Pole Adjustable Voltage & Current Protection Relay

Short Description

The CNC Electric YC6VA is a microprocessor-based protection relay for single-phase AC networks. It monitors and displays voltage and current, provides adjustable over-voltage, under-voltage and over-current protection, and automatically reconnects the load after normal supply conditions return.

Long Description

The CNC Electric YC6VA combines real-time voltage and current monitoring with adjustable protection in a compact two-module DIN-rail enclosure. Designed for single-phase AC distribution, it analyses the incoming supply and disconnects the load through an electromagnetic relay when voltage or current exceeds the programmed limits.

Users can configure over-voltage, under-voltage, over-current, trip timing, recovery delay and power-on delay settings from the front controls. The dual digital display provides clear voltage and current readings, while dedicated status indicators show over-voltage, under-voltage, over-current and power conditions.

After the fault clears, automatic recovery restores the output following the selected delay. Settings are retained in non-volatile memory. The YC6VA is suitable for residential, commercial and industrial single-phase distribution systems, including the AC side of compatible solar and backup-power installations. Installation and parameter selection should be performed by a qualified electrician.
