Schneider Electric K1B002QLH Harmony K K1 1-Pole 12A 45deg Cam Stepping Switch

The Schneider Electric K1B002QLH 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 two steps plus an off position, uses a black handle with a 0-1-2 metallic legend, and mounts to a front panel via multifixing for local two-step or two-source selection.

Selection Notes

The K1B002QLH's 0-1-2 stepping function with an off position suits two-step selection or dual-source changeover panels where an operator needs a visible off state between steps. Its single-pole, 45° switching angle and 12 A Ith rating fit small control or signal circuits rather than direct motor switching — at 400 V AC-3 the rated operational current drops to 3.3 A, so size it for pilot or auxiliary circuits, not the main power feed. Multifixing mounting lets it drop into a standard 45 x 45 mm cutout alongside other Harmony K series switches on the same panel.

Applications

Used as a manual selector or stepping switch on control-panel doors for two-speed selection, dual-source changeover, or sequence-step control in machine-building and panel-shop applications.
