JK42-JLA153 (JSMA-F)

3-phase earthing device

Ref. SS 428 91 01, SS-EN 61230
The connector is intended for switchgear.
Conductor clamp JK 42 is connected to connectors JKA, JKC, JKAD, JBA, and JBC or directly to cables or pipes with max Ø 40 mm. To operate the clamp, insulating rods MGV, MDV/MSV and grippers JGS are used.
The conductive parts of the clamp are made of hardened AlSi alloy and steel parts of stainless steel. The thread is fitted with a stainless steel Heli-Coil insert.
The cable is made of highly flexible ESTPR-insulated copper conductor and fitted with tight cable connections, which prevent moisture penetration into the cable. The cable is crimped to the conductor clamp. Earth clamp JK 153 is used, among other things, on steel structures with a maximum thickness of 20 mm and is approved for use on painted surfaces. The screw on this clamp is provided with insulation to prevent current flow.
