FIELD: electrical engineering.
SUBSTANCE: invention is a residual current switch. Residual current switch for low voltage electrical lines comprises: a shaped casing, at least a couple of electric contacts comprising a moving contact and a fixed contact, which are adapted to be electrically connected to a phase conductor of an electric circuit and which are adapted to be mutually coupled with or separated from one another, residual current protection means positioned in said shaped casing, which are preferably adapted to detect a residual current among the conductors of the electric line and generate a first tripping signal on the basis of the trend of said residual current. Residual current switch also comprises a first connection element, which comprises a first connection portion, wherein said first connection element is connectable to a first conductor operatively coupled to said residual current protection means, and a second connection portion, at which said first connection element is connectable to a second connection element adapted to be connected to the neutral conductor of the electric line.
EFFECT: invention is intended to increase the level of safety.
