The connector SEW20.1 includes an arc protection horn and is used for arc protection for covered conductors. The connector SEW20.2 includes an Al-thread to connect the connector to the neck of the insulator. The length of 25 mm² Al thread is 2.1 m. SEW20.3 is used as a temporary earthing connector where the arc protection devices SE20.1 or SE20.2 are not present. The connector SEW20.3 includes an arc protection horn suitable for use with temporary earthing devices with screw fixing. The connector has a place for an Al-thread, so it also works as an arc protection device. Tested short circuit...
