Leakage current control relay RKTU-1
New
Recommend
The operation of the relay is based on continuous monitoring of the current in the DC, AC or rectified voltage circuits (including monitoring the isolation of gas protection circuits) and issuing a trigger signal when the controlled current exceeds the value of the selected setpoint (set by the user using the DIP switch on the front panel). The operation of the relay indicates an unacceptable decrease in the insulation resistance, leads to the withdrawal of the gas protection from action and acts as a warning alarm.
The wide range of operating setpoints of "RKTU-1" makes it possible to use it at various nominal values of the operating voltage from 24 to 220 V. The selection of the actuation setpoint can be carried out on the basis of the requirements of the PUE, according to which the insulation resistance of each connection of the secondary circuits must be at least 0.5 mOhm.
The wide range of operating setpoints of "RKTU-1" makes it possible to use it at various nominal values of the operating voltage from 24 to 220 V. The selection of the actuation setpoint can be carried out on the basis of the requirements of the PUE, according to which the insulation resistance of each connection of the secondary circuits must be at least 0.5 mOhm.
