REDs, REDtestProtectEarth leakage protectionAutomatic recloser
The REDs and the REDtest, REsidual current Device recloser, is made up of a residual current device and a recloser.The REDs and REDtest REsidual current Devices offer the following functions:
b protection of people against direct and indirect contacts b protection of installations against insulation faults b disconnection of on-load electric circuits, already protected against overloads and
short-circuits b automatic restart after insulation monitoring of the downstream circuit.
REDtest provides the following additional functions: b automatic and periodical test of the device, without breaking downstream circuit
(REDtest).Only used on TT and TN-S earthing grounding systems.

OperationREDsThe REDs operates in the residual current device mode, without automatic restart,when the sliding cover is open, i.e. to the right in the Auto Off position (Fig. 1).
The automatic restart mode and the Autotest are activated, when the sliding cover isclosed, i.e. to the left in the Auto On position (Fig. 2).
Test
REDtest b The REDtest carries out automatic testing of earth leakage protection every
months.The test consists in opening and reclosing the REDtest, during which time continuity of supply of the downstream installation is guaranteed.Autotest: after checking installation insulation, the REDtest monitors its residual current device, without breaking the downstream power supply (bypass by bypass contact).
d This is only possible in manual mode, i.e. sliding cover open in the Auto Off position. You can then manually test the device by pressing the Test key. The downstream installation is then temporarily broken. You must then manually reclose the RED by activating the O-l lever to power supply the downstream circuit.

Operation ON mode: long network faultREDsIf the circuit is faulty, the switch is prohibited from reclosing. After a time delay of 15 minutes, the downstream circuit insulation is rechecked. There are then two possibilities:
b the installation is still faulty (the resistance to earth is lower than Rd): in this case a new check will be carried out in 15 minutes.
b the fault was temporary and has disappeared (the resistance to earth is higher than Rdo): the recloser automatically recloses the REDs.
