The Push-in direct connection technology make the insertion forces reduced by up to 50 percent and tool-free wiring, enable the conductors to be inserted easily and directly. Made from engineering flame retardants nylon PA66 with brass screw metal. Made from engineering flame retardants nylon PA66 with brass screw metal. ●The Push-in connection terminal blocks are characterized by easy and tool-free wiring of conductors with ferrules or solid conductors. ●The compact design and front connection enable wiring in a confined space. ●In addition to the testing facility in the double function shaft, all terminal blocks provide an additional test connection. ●With universal foot which can be installed on Din Rail NS 35. ●It can connect two conductors with ease, even large conductor cross sections are not a problem. ●Electric potential distribution can use fixed bridges in the terminal center. ●All types of accessories: End cover, End Stopper, Partition plate, marker trip, fixed bridge, insertion bridge, etc.
