YCMV3

The YC6VA is a single-phase digital voltage protection relay designed to protect electrical systems from overvoltage and undervoltage conditions. It continuously monitors supply voltage and automatically disconnects the load when voltage exceeds or drops below preset limits. Once voltage returns to the safe operating range, the relay reconnects after a preset delay time.

The YC6VA is suitable for residential, commercial, and light industrial distribution boards where sensitive loads require voltage stability.
