JFS21-X-JLA34 (JSE-KM)
3-phase earthing device
Ref. SS 428 91 01, SS-EN 61230
Conductor clamp JFS 21 is connected to hooks JKS and JKR. Insulating rods MGV, MDV/MSV and gripper JGS are used to operate the clamp.
The conductive parts of the clamp are made of hot-pressed electrolytic copper. Steel parts are made of stainless steel. The conductor clamp is equipped with stainless steel disk washers, which provide a constant contact pressure. The ESTPR-insulated copper conductor is provided with tight cable connections, which prevent moisture ingress into the cable. The cable is crimped to the earthing device. Cable lug JLA 34 and branch piece JFG 4 (rubber covered) are made of hot-pressed electrolytic copper for max 120mm² cable, handle nut of stainless steel. JLA is connected to fixed connectors to earth, JVF and JBF.
