The CNC YC9-VA 2P 63A Voltage and Current Protection Relay is a high-performance device designed to protect single-phase AC systems from voltage fluctuations and current anomalies. It features built-in overvoltage, undervoltage, overload, and short circuit protection. Equipped with a digital display, the relay provides accurate real-time monitoring of voltage and current values. Users can configure the operating voltage range and response delay time through a simple interface, with all settings stored in non-volatile memory to ensure reliability during power outages. Ideal for installation in residential buildings, commercial facilities, and industrial environments, this device ensures stable and secure operation of electrical systems. The YC9-VA supports both aluminum and copper wire connections and complies with standard instantaneous release classifications (Type B, C, D).
