An addition to the popular WKFN DIN rail terminal block series, the new WKFN 4TKG is a disconnect block that can be fitted with fuse and component holders. The WKFN 4 TKG disconnect block is compatible with the existing WKFN 4 terminal block series and 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. The WKFN 4 TKG block provides two-tier jumper channels and has integrated test bolts to make testing simple and, when combined with the 16mm² potential distribution block, it enables the user to implement fused outputs for a power supply up to 76 A.
A swiveling fuse disconnect lever or a pluggable fuse holder designed for device fuses of 5x20 mm or 6.3x32 mm is available. All fuse holders are available with an optical indicator for display of fuse defects for various voltages. Alternatively, the Wieland component holder can be inserted in the terminal block. It is available with diode or jumper or it can be supplied empty for individual pre-assembly.
Wieland Electric is the expert in electrical connection technology, with a product range that includes in excess of 20,000 components for the industrial and building automation industries.
