Voltage relay with current control WELROK VI-50 Red, VI-50, etc.

Single-phase voltage relays with current control and thermal protection are designed to protect the single-phase power grid from unacceptable voltage deviations, as well as excess current consumption and active power. Voltage relays with current and power control WELROK protect the equipment from voltage surges and dips, the consequences of a zero wire break and excess current or power. The relays turn off the load if the voltage, current or power exceeds the set limits and automatically turn on the load when the parameter value returns to normal.

Models: VI-40 red, VI-40, VI-50 red, VI-50, VI-63 red, VI-63.
