Schneider Electric K2C003ALH Harmony K K2 3-Pole 20A 45deg Cam Switch

The Schneider Electric K2C003ALH is a Harmony K2 cam switch with three poles, a 45° switching angle, and a 20 A conventional free-air thermal current (Ith). It switches all three poles together between an off position and one on position (0-1 marking), and mounts to a front panel by multifixing for three-phase disconnect or selector duty.

Selection Notes

At 20 A Ith on the K2 frame, the K2C003ALH handles a higher pilot or small three-phase load than the 12 A K1-frame switches in the same Harmony K range, while keeping the same 45° on/off function and visible off position. CCC and GB/T 14048.3/14048.5 certification on this variant supports installations needing Chinese national approval. Choose the K1 frame instead when panel space is tighter and the circuit stays under 12 A.

Applications

Used as a manual three-phase disconnect or selector switch on control-panel doors in machine-building and panel-shop assemblies where the load exceeds the K1 frame's current rating.
