1-phase JK42-JK238

1-Phase Earthing Device

Ref. SS 428 91 01, EN 61230
The device is for use on outdoor framework and high constructions indoors.
Line clamp JK 42 is for connection to contact fittings JKA, JKC, JKAD, JBA, and JBC or directly on lines or pipes with max Ø 40 mm. Insulating poles MGV, MDV/MSV and operating socket JGS are used to operate the line clamp.
The line clamp conducting parts are made of hardened AlSi-alloy and steel components are made of stainless steel. The thread has a Heli-Coil insert in stainless steel. The earthing cable, made of highly flexible ESTPR-insulated copper strands, has sealed cable connections, which prevent humidity from penetrating the cable. The earthing cable is connected by compression to the earthing device.
Earth clamp JK 238 is for framework up to 30 mm and is also approved for use on painted surfaces. The bolt on this clamp is equipped with insulation to prevent the passage of current.
