Schneider Electric K30F003UP Harmony K K30 3-Pole 32A Front Mount Cam Switch

The Schneider Electric K30F003UP is a Harmony K series front-mounted cam changeover switch with 3 poles, rated for 32 A conventional free-air thermal current (Ith) and 690 V insulation voltage (Ui). The 64 x 64 mm plastic front plate carries a black handle marked 1-0-2, switching 60 degrees between two positions with an off position in the center, IP40 rated.

Selection Notes

The 3-pole configuration switches all three line conductors together, which is what three-phase changeover duty requires - for example alternating a three-phase load between mains and generator, or selecting between two three-phase feeders. With 32 A Ith and 690 V Ui it covers general-purpose three-phase motor and distribution changeover in enclosed panels; the 2-pole version exists for circuits where only two conductors need to switch. Pick the 3P body whenever the load is three-phase and all three lines must transfer at once.

Applications

Typical uses include transferring a three-phase motor or distribution board between mains and generator supply, or selecting between two three-phase feeders in a dual-source panel. The captive screw clamp terminals accept 2 x 4 mm2 flexible or 2 x 6 mm2 solid conductors, so panel wiring does not need ferrules. The 4-hole front mounting and 64 x 64 mm cutout match the standard Harmony K panel footprint.
