Schneider Electric K1B001ULH Harmony K K1 1-Pole Changeover Cam Switch 12 A 45 Degree

The Schneider Electric K1B001ULH is a Harmony K1 cam changeover switch with a single pole, an off position, and a 45-degree switching angle. Rated for 12 A conventional free-air thermal current (Ith) and 690 V insulation voltage, it mounts to a 45 x 45 mm front plate with multi-fixing and carries IP40 protection for panel-door control stations.

Selection Notes

The K1B001ULH is the 1-pole changeover variant in the Harmony K1 cam-switch line, moving between two positions plus an off position across a 45-degree arc, unlike the 2-pole configuration used where two independent circuits need switching together. Its 12 A Ith rating and 690 V insulation voltage (pollution degree 3) size it for control-circuit switching rather than direct motor starting, and the 16 A gG fuse back-up sets the coordinated short-circuit protection. IP40 keeps it suited to enclosed panel fronts rather than washdown areas.

Applications

Used as a manual selector or changeover element on control panel doors, for example switching between two control modes or supply sources, where the 45-degree throw and metallic 2-0-1 legend give operators clear position feedback. Multi-fixing front-plate mounting on a 45 x 45 mm cut-out fits standard pilot-device panel layouts alongside pushbuttons and pilot lights.
