The necessity to ensure reliable service availability to priority loads has lead to ABB developing the new auto-reclosing device known as the F2C-ARI.

The F2C-ARI enables automatic reclosing of a residual current device in case of nuisance tripping (for example after an overvoltage created by lightning). The new auto-reclosing device is particularly suitable for use in unmanned control panels. Applications include mobile phone and television repeater stations, traffic and signalling control, pumping and irrigation stations, refrigeration and cool rooms, public lighting etc.

The F2C-ARI device is only two modules wide and is fitted to the right side of an ABB residual current circuit breaker. It will automatically perform three reclosing attempts in the event of a fault. If the RCD trips again after three attempts to reclose, the F2C-ARI goes to a locked state and provides a signal contact for warning purposes. The auto-recloser can be easily reset either locally or remotely (up to 1500 metres away) after being locked following three failed auto-closing attempts. After resetting, the auto-recloser is ready for a further three reclosing attempts.

A multi colour LED of the front of the device offers a variety of signal conditions of the state of the recloser. Auxiliary contacts are also provided to indicate the ON or OFF state of the RCD. For efficiency and convenience all control wiring connections are made via plugs. The auto-recloser can be simply and safely installed on site to ABB RCD devices up to 100A.

For additional safety the F2C-ARI incorporates a padlocking facility to allow effective tag-out procedures on the protected load.
