The 4-pole configuration gives you two normally-open and two normally-closed power poles, which is what makes the changeover (reversing) function work without external wiring. The 20 V DC coil is standard for many control systems; the built-in diode suppressor means you do not need an external flyback diode across the coil, saving a component and a wiring step on the panel. The rated making capacity is 144 A AC, which covers inrush from cold resistive loads. Mechanical durability is 5 million cycles; electrical durability is 300,000 cycles at full AC-1 load — a solid figure for a panel that cycles a few times per hour. IP20 finger-safe terminals per VDE 0106. Tightening torque is 1.3 N.m. This is a reversing contactor assembly — two contactors mechanically interlocked so both cannot close at once, with a pre-wired busbar that swaps two phases for motor reversal. It is designed for control panels where a motor or resistive load needs to run forward and reverse (conveyor drives, valve actuators, hoist controls). The mechanical interlock is built in; the reversing busbar is already installed, so the panel builder just mounts the assembly, lands the power and control wires, and connects the load.","metaTitle":"Schneider TeSys K LP2K12004ZD3 Changeover Contactor, 20 V DC","metaDescription":"Schneider TeSys K LP2K12004ZD3 changeover contactor, 4P, 20 V DC coil, AC-1 rated 20 A.
