Schneider Electric K1C003ALH Harmony K K1 3-Pole 12A 45deg Cam Switch

The Schneider Electric K1C003ALH is a Harmony K1 cam switch with three poles, a 45° switching angle, and a 12 A conventional free-air thermal current (Ith). It switches between an off position and one on position (0-1 marking) via a black handle with metallic legend, and mounts to a front panel by multifixing for three-phase circuit on/off control.

Selection Notes

The K1C003ALH switches three poles simultaneously between off and one on position, making it a straightforward three-phase disconnect or selector rather than a stepping switch — pick a stepping variant in the K1 range instead if the application needs multiple on positions. Its 12 A Ith and 690 V Ui rating size it for pilot power or small three-phase loads on a control panel, not as the main motor disconnect. CCC and GB/T 14048.3/14048.5 certification on this variant supports use in installations that require Chinese national approval alongside the IEC/CENELEC base standards.

Applications

Used as a manual three-phase selector or disconnect switch on control-panel doors in machine-building and panel-shop assemblies where a compact 45 x 45 mm cam switch replaces a separate toggle or rotary disconnect.
