RCDs with automatic test

Save maintenance costs with maximum safety

It is essential that regular testing of residual current circuit breakers is carried out every six months to ensure that the contacts are functioning properly and that the device can trip in the event of an earth fault.

The F-ATI and F-ARI RCDs with automatic testing take periodic testing to a new level, as it is performed automatically and without any interruption of service. The work to be performed by maintenance personnel is thus reduced to a minimum and a whole range of devices can be remotely controlled and read out via the ARBus interface.

In addition to the automatic test, the F-ARI reclosing operations are based on an insulation test to ensure that no permanent fault is present.
