ABB 2CSF302131R1630 F-ARI2Test A-63/0.03 RCCB A 2-pin 63 A 0.03 A 230 V

F-ATI and F-ARI are RCCBs with automatic non-disruptive testing. RCCBs should be tested at least every six months, depending on the application. This ensures that the contacts are functioning properly and that the device is triggered in the event of a fault current against earth. Regular testing of the RCCBs affects the uninterrupted operation of the downstream circuits and involves a great deal of work. This work is not required when using F-ATI and F-ARI. These FIS perform the regular tests automatically and without interrupting the system. The operation by the maintenance personnel can therefore be reduced to a minimum. In addition to the automatic tests, the F-ARI series is equipped with an automatic restart unit to close the RCCB again after it has been triggered. This is especially suitable for areas to which only electro-technically trained persons or electrical experts have access. The system will restart based on an insulation test to ensure that it is not a permanent fault. The Arbus interface also collects the results of all circuits.
