Protection of people against direct and indirect
contacts. Protection of installations against insulation
faults. Disconnection of on-load electric circuits,
already protected against overloads and short-circuits.
Automatic restart after insulation monitoring of the
downstream circuit. Periodic automatic testing of the
device without downstream circuit power supply
breaking.
Description
The REDtest,
RE
sidual current
D
evice recloser, is made up of a residual current
device, a recloser and a product automatic test function (Autotest).
A type
The REDtest
phase-to-neutral
residual current devices provide
A type
earth leakage
protection: tripping due to sinusoidal AC residual currents as well as by continuous
pulsed residual currents, whether they are applied quickly or increased slowly.
