The relay control current leakage type "RCTU-01" is intended to implement the following functions:
control of insulation resistance;
monitoring the integrity of the General section of the tavern.
The principle of operation of the relay based on the constant current control in DC, AC or rectified voltage (including isolation control circuits of the gas protection) and signal alarms when exceeding the controlled current values for the selected setpoint (set by the user via DIP switch on the front panel). The relay indicates an unacceptable decrease in the insulation resistance, leads to the conclusion that gas protection of the actions and acts in the circuit alarms.
A wide range of actuation setpoints "RCTU-01" makes possible its use for different nominal values operating voltage from 24 to 220 C. setpoint alarms can be implemented based on the requirements of the national electrical code, according to which the insulation resistance of each accession secondary circuits shall be not less than 0.5 MW. Thus, for example, for a nominal operating voltage of 220 V is the allowable leakage current is not more than 440 μa, respectively setpoint relay "RCTU-01" is set equal to 500 µa.
If the contact is closed gas relay in the input chain RCTU-01" current flows determined by the load circuit gas protection and clearly exceeds the fixed setpoint lock. The device is thus automatically provided the ban on the issuance of the signal of the trigger circuit isolation control. The input circuit "RCTU-01" allow continuous flow of current up to 3 A, the voltage drop on the input circuit of the device at the maximum current does not exceed the 4 Century
