Mounting position of bridging bar on transfer switching equipment

The bridging bar serves as a bridge for a load-side connection on transfer switching equipment in accordance with IEC 60947-6-1. This can be implemented with the 3KC3 and 3KC6 transfer switching equipment.

In the case of a load transfer switch, the bridging bar can also be used as a bridge on the line side in order to transfer two loads (IEC 60947-3). This can only be implemented with the 3KC3 transfer switching equipment.

NOTE

With the 3KC6 transfer switching equipment, the main circuit must be connected on the underside of the transfer switching equipment when the motor is installed on the right (on terminals 1, 3, 5, 7). The bridging bar can therefore only be connected on top in the case of the 3KC6 transfer switching equipment.

You can find information on installation of the bridging bar in the section titled Connecting the bridging bar on the load side.
