CP-733 voltage relay CP-733

Intended use
The CP-733 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
Relay power supply is indicated by LED lighting green U. Correct mains voltages are signaled by lighting of the yellow LEDs L1, L2 and L3 in the circuit of each phase (relay contacts are open). Voltage decay in a phase or its drop below the set activation voltage threshold will activate the relay contact corresponding to this phase (yellow LED is off in the circuit of this phase). The contact will be disconnected 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.
