Plug-in metal busbar terminal blocks designed to be mounted on 3x12 and 5x5 copper busbars are produced in 3 different sizes, suitable for 4mm², 16mm² and 35mm² sections. Hexagon M10 bolts are used in terminal blocks with 35 mm² cross section. Thus, since a very large area presses the entire cable, there is no need to use pallets. It also allows the tightening of the bolt used at very high torque due to its hexagon socket head cap.
Thus, it does not cause tightening with low torque that may occur while using the screwdriver, injuries slipping out of the screwdriver or situations such as screw head failure.
