Application YC9VA voltage and current display relay used in administrative, industrial and residential buildings and has the function of protecting single-phase lines: Undervoltage protection; Overvoltage protection; Working under voltmeter mode. Operation and Installation Functions When a voltage is applied to the device, the digital indicator will display the current value of the voltage in the network. A flashing light indicates that there is no voltage on the output of the device. If th...

Function 1. Personnel and fire protection 2. Cable and line protection against overload and short-circuits. Selection 1. I∆n ≤ 30 mA: additional protection in the case of direct contact. 2. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents. 3. AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase. Curve Specifications
