1-Phase Earthing Device
Ref. SS 428 91 01, EN 61230
Earthing devices JK238-DXF and JK250-DXF are used in combination with earthing device JSKL3-, JSGT and JSGH. Suitable as a down line to earth when there is no “0” conductor. The device is for connection to framework up to 30 mm thick or temporary earthing rod screw DJS 1. The clamps (JK 238, JK 250) are approved for mounting on painted surfaces.
The device has a rubber insulated bayonet type connector fitting for connection to earthing device JSKL3-, JSGT and JSGH.
Conducting parts of the clamps are made of surface treated spring steel with hardened spikes. Other steel components are made of stainless steel. The loop is made of spring steel to give a constant contact pressure. The screw is insulated. The earthing cable, made of highly flexible ESTPR-insulated copper strands, has sealed cable lugs, which prevent humidity from penetrating the cable. The earthing cable is connected to the clamp with a cable lug.
Case: DFO-JSKL1-J.
