The new WKFN 4TKG from Wieland is a disconnect block that can be fitted with fuse and component holders. The new product is compatible with existing terminal block series and is equipped with the same features, including marking options, potential distribution and testing options. The block is designed to be mounted on standard TS35 mounting rail and can be used to connect solid wires up to 6mm² and fine-stranded wires up to 4mm², including ferrule. When combined with the 16mm² potential distribution block, the WKFN 4 TKG enables the implementation of fused outputs for a power supply of up to 76A.
