- Description
The Schneider Electric K1D004QLH is a Harmony K1 cam stepping switch with a single pole, four switching steps spanning 0 to 180 degrees 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 4-step configuration adds a fourth 45-degree position over the 3-step K1 stepping switch, giving an extra selectable position for control or indicator-lamp circuit switching from a single pole. Use the 3-step version when only three positions are needed; both share the same 45 x 45 mm plate and 12 A Ith rating. The 690 V insulation rating and 16 A gG fuse back-up match the K1 body's 10 kA short-circuit withstand.
