ABB Stotz S&J RCCBs F-ARI4Test A-25/0.03: further details
F-ATI and F-ARI are RCCBs with an automatic uninterruptible test function. RCCBs should be tested at least every six months, depending on the application. This ensures that the contacts are functioning properly and that the unit will trip in the event of a fault current to earth. Regular testing of RCCBs affects the uninterrupted operation of downstream circuits and requires a lot of work. When using the F-ATI and F-ARI, this workload is eliminated. These RCDs carry out the regular tests automatically and without interrupting the system. Operation by maintenance personnel can therefore be reduced to a minimum. In addition to the automatic tests, the F-ARI series is equipped with an automatic reclosure unit to reclose the RCCB after it has tripped. This is specially designed for areas to which only electrically instructed persons or qualified electricians have access. Reclosing is based on an insulation test to ensure that the fault is not permanent. The results of all circuits are also collected via the ARBus interface.
