A disconnector device is connectable to pole-mounted equipment in a power grid. The disconnector device is activated in case of an overload condition, thereby disconnecting the pole-mounted equipment. The disconnector device comprises a passive radio device to be enabled via an incoming radio signal. The passive radio device, upon being enabled, transmits, in at least one state of the disconnector device, an indicator radio signal indicative of the respective state of the disconnector device, the state being one of an activated state and a deactivated state of the disconnector device.
