CP-734 voltage relay CP-734

Intended use
The CP-734 voltage relay is used to control the voltage of a three-phase network and protect a single-phase receiver against the effects of a voltage drop below the set value. Operation
The power supply of the relay is indicated by the green U LED. Proper mains voltages are indicated by the yellow L1, L2 and L3 LEDs in the circuit of each phase (relay contacts closed). Voltage decay in a phase or its drop below the set activation voltage threshold will cause opening of the relay contact corresponding to this phase (yellow LED is off in the circuit of this phase). The contact will be activated automatically after the voltage returns in the phase or the voltage increases by 5V above the set threshold (i.e. by the value of the voltage hysteresis). this phase as long as the button is held down.
