CURRENT TRANSFORMER HAVING A SHORT-CIRCUIT DEVICE

The invention relates to a current transformer 1, having connection contacts 2 for contacting a secondary winding and having a short-circuit device 3′, 3″ for shorting the connection contacts 2, wherein the short-circuit device 3′, 3″ has a mechanically movable conductor 4 that can be brought into a circuit between the connection contacts 2 of the secondary winding. Here, the short-circuit device 3′, 3″ is integrated in a housing 14 surrounding the current transformer 1 and the movable conductor 4 can be moved by a rotary or pivot motion into the circuit between the connection contacts 2, such that the circuit of the secondary coil is shorted.
