Socket outlet with side earthing, shutters and overvoltage protection
This socket outlet is used to protect sensitive electronic equipment (e.g. TV, hi-fi, pc, washing machines, dishwashers and medical equipment) against voltage peaks on the mains due to mains failure or indirect lightning strokes. It does not protect against voltage peaks entering the equipment via other ways (e.g. cable distribution, data lines and telephone lines). The socket outlet exclusively protects the connected device within the technical specifications as described below. The socket outlet carries the CEBEC quality mark in accordance with the IEC61643-1 and EN61643-11 standards (class III, type 3). The varistors that limit the voltage between the phase (L) and zero conductor (N) are thermally monitored. If the red LED lights up, the protection is no longer functioning (the protected device remains connected to the mains) and the overvoltage module needs to be replaced.
