Schneider Electric K1B002ALH Harmony K K1 2-Pole Cam Switch 12 A 45 Degree

The Schneider Electric K1B002ALH is a Harmony K1 cam switch with two poles, 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 K1B002ALH is the 2-pole configuration in the Harmony K1 cam-switch line, switching two independent circuits together across a single 0-45-degree throw rather than the changeover (double-throw) action of the 1-pole variant. Its 12 A Ith rating and 690 V insulation voltage (pollution degree 3) size it for control-circuit switching, and the 16 A gG fuse back-up sets the coordinated short-circuit protection. CCC and GB/T 14048.3 / 14048.5 certification alongside the IEC 60947 base standards extend its use to China-market panel builds. IP40 keeps it suited to enclosed panel fronts rather than washdown areas.

Applications

Used as a manual on/off selector on control panel doors, for two circuits switched together such as a two-speed selection or dual-supply isolation, where the 45-degree throw and 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.
