Overvoltage protector – 3F

3F-control-relay-22-33

mod. 22 single phase
This device, for motor protection, controls that the drop voltage doesn’t exceed the established value, by turning off the relay when it happens. The relay is delayed to prevent the brief and temporary breaking.

mod. 33 3-phase
This unit is designed to monitor a 3 phase supply, one failure phase and a lowering of power supply.The relay allows the motor start only if there are the above mentioned conditions. The relay is delayed to prevent brief temporary interruptions.
