The Schneider Electric LP1K1201JD3 is a TeSys K contactor — three-pole, rated 12 A in AC-3 duty at ≤440 V, with a 12 V DC coil. The same contactor also carries an AC-1 rating (resistive load) and an AC-4 rating (plugging/inching duty), giving you flexibility for different load types on the same pole set. The 12 V DC coil draws 3 W inrush and 3 W hold-in power at 20 °C. The built-in bidirectional peak limiting diode suppressor means you don't need an external flyback diode across the coil — the suppression is integrated, which simplifies panel wiring and protects the DC control circuit from voltage spikes when the coil de-energises.
Where this class of part is used
TeSys K contactors are compact panel-mount components for switching motor loads, resistive heaters, and lighting in industrial control panels. The 45 mm width and 58 mm height fit standard DIN-rail or screw-mount footprints, common in machine control cabinets and HVAC panels.
Physical fit
The three-pole block with one NC auxiliary contact fits the standard TeSys K footprint, so it retrofits into existing TeSys K panel layouts without re-drilling or re-terminating the bus bars.
