JK42-JLA31 (JSBV-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 wire or pipe 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 don cable is crimped to the conductor clamp. Cable lug JLA 31 is made of hot-pressed electrolytic copper.
JLA is connected to fixed connectors to earth, JVF and JBF.
