Schneider Electric K1C003NLH Harmony K K1 1-Pole 12A 3-Step Cam Stepping Switch

The Schneider Electric K1C003NLH is a Harmony K1 cam stepping switch with a single pole, a 45° switching angle, and a 12 A conventional free-air thermal current (Ith). It has three steps (1-2-3 marking) with no off position, so the circuit stays live at every switch position, and it mounts to a front panel by multifixing for continuous three-position selection.

Selection Notes

Unlike the off-position stepping switch in the K1 range, the K1C003NLH has no off position — the circuit is always connected to step 1, 2, or 3, so use it where a de-energized state is never required, such as selecting between three fixed setpoints that must always have one active. Its single pole and 12 A Ith rating suit pilot or signal circuits rather than direct motor power. The 0°-45°-90° switching range gives three distinct 45° detents for the three positions.

Applications

Used as a three-position selector switch on control-panel doors for choosing between three fixed setpoints, ranges, or signal sources where the circuit must always remain connected to one of the positions.
