CP-733 F&F voltage relay
Product description
Three-phase, under-voltage. 3×NO contact.
The CP-733 voltage relay is used to control the voltage of a three-phase network and protect consumers from the effects of a voltage drop below the set value.
Application
The relay is used in BMS or PLC installations to report abnormalities in the three-phase mains.
Operation
Power supply of the relay is signaled by lighting of the green U LED. Correct mains voltages are indicated by the illumination of the yellow LED L1, L2 and L3 in the circuit of each phase (open relay contacts). The loss of voltage in a phase or its drop below the set trip voltage threshold will switch on the relay contact corresponding to this phase (the yellow LED in the circuit of this phase is not lit). The contact will be disconnected automatically when the phase voltage returns or the voltage rises by 5V above the set threshold (i.e. by the voltage hysteresis value).
TEST (simulation of tripping)
Pressing the momentary TEST button in the circuit of a given phase causes the contact corresponding to this phase to be switched on for the time the button is held.
