JSK-JK153 (JSET)

3-phase earthing device

Ref. SS 428 91 01, SS-EN 61230
Conductor clamp JSK is connected directly to the phase rail when there is no connector. Insulating rods MGV, MDV/MSV and grippers JGS are used to operate the clamp.
The conductive parts of the clamp are made of hot-pressed electrolytic copper. The shackle is made of hardened AlSi alloy and fitted with a hub plate of hardened surface-treated steel. The thread is fitted with a stainless steel Heli-Coil insert, other steel parts are stainless steel. The conductor clamp is fitted with stainless steel disk washers, which provide a constant contact pressure. The cable is made of highly flexible ESTPR-insulated copper conductor and provided with tight
cable connections, which prevents moisture penetration into the cable. The earthing cable is crimped to the earthing device. Earth clamp JK 153 is used, among other things, on steel structures with a material thickness of max. 20 mm and is also approved for use on painted surfaces. The screw on this clamp is provided with insulation to prevent current flow.
