Schneider Electric K1C003QLH Harmony K K1 12A 1P 3-Step Cam Stepping Switch

The Schneider Electric K1C003QLH is a Harmony K1 cam stepping switch with a single pole, three switching steps at 45-degree increments, and a 12 A conventional free air thermal current (Ith). Front-mounted with a 45 x 45 mm plate and screw-clamp terminals, it switches AC-21 loads up to 8.3 kW at 400 V within an IP40 enclosure.

Selection Notes

The 1-pole, 3-step configuration suits simple sequential control, selecting between three positions in 45-degree increments off a single pole, such as switching a single-phase load between two speeds or supply sources plus an off position. Choose the 4-step variant of the same K1 stepping switch when a fourth position is needed, or a K1 changeover version when only two directions without intermediate steps are required. The 690 V insulation rating and 10 kA short-circuit withstand behind a 16 A gG fuse suit control-panel front-plate mounting ahead of contactor-controlled motor circuits rather than direct motor switching at full load.
