ARA automatic reclosers
For iC60 circuit breakers
and iID residual current circuit breakers
Control
Remote control
The ARA reclosing auxiliary can:
b
b
Perform automatic reclosing of the associated protection device, after tripping.
b
b
Increase the availability of installations without supervision, isolated, hard of
access and demanding very great availability (mobile telephony systems,
motorways, pumping stations, airports, railways, meteorological stations, service
stations, automatic teller machines, public lighting, tunnels, etc.), by restoring
them to operation without intervention by personnel in the event of a transient
fault (atmospheric disturbances, industrial overvoltages, etc.).
b
b
For the ARA iC60, the operator can choose predefined reclosing program which
allows the safety and availability of facilities to be reconciled taking into account
the facility's environment.
b
b
The circuit is placed in safety configuration by the padlocking device.
