The HHZ control relay controls frequency variations on 50 Hz or 60 Hz networks.
This HSV frequency monitoring relay from Crouzet has been designed to control its own supply voltage, connected between phase and neutral. Equipped with a host of excellent features, including over and under frequency with two independent relay outputs, selectable latching (memory) function, LED status indication and IP30 (casing)/IP20 (terminals) protection.
