Schneider Electric K2F003ULH Harmony K K2 20A 3P 45° Cam Changeover Switch

The Schneider Electric K2F003ULH is a Harmony K2 cam changeover switch with three poles, a 45-degree switching angle, and a 20 A conventional free air thermal current (Ith). Front-mounted with a 45 x 45 mm plate and screw-clamp terminals, it withstands a 10,000 A short-circuit current behind a 20 A gG fuse and carries an IP40 enclosure rating.

Selection Notes

The 3-pole changeover configuration switches a three-phase circuit between two sources or motor rotation directions at up to 20 A Ith. Choose the 2-pole version for single-phase circuits or the 4-pole version when a neutral or fourth conductor must also be switched; all share the same K2 body and 45 x 45 mm front plate. The 10 kA short-circuit withstand is backed by a 20 A gG cartridge fuse upstream. Screw-clamp terminals accept flexible conductors up to 1.5 mm² or solid conductors up to 2.5 mm², matching the 2-pole and 4-pole K2 versions.
