The Automatic Recloser Auxiliary (ARA) performs automatic reclosing of the associated protection device after tripping, avoiding service interruptions.
This range of Acti9 ARA auto reclosers increase the availability of installations without supervision, isolated, hard of
access and demanding very great availability reducing maintenance costs.
Acti 9 ARA automatically recloses and re-energizes the circuit after a momentary outage, at intervals predetermined by the users.
In a permanent fault case, the ARA locks open after user preset number of operations, safely isolating the section from the system.
