Schneider Electric 9001KA1 Harmony 9001K 1 NO 1 NC Auxiliary Contact Block

The Schneider Electric 9001KA1 is a contact block for the Harmony 9001K and 9001SK pushbutton range, adding 1 C/O (1 NC + 1 NO) contacts rated 3 A at 240 V AC-15. It mounts behind the operator head on 30 mm cutout stations and uses screw-clamp terminals rated up to 2.5 mm2, giving a 10 A conventional free-air thermal current and a 600 V rated insulation voltage.

Selection Notes

The 9001KA1 is a single-contact add-on block for Harmony 9001K/9001SK pushbutton and selector operators, giving one changeover contact (1 NC + 1 NO) for pilot-duty and relay-coil switching at 3 A / 240 V AC-15 or 0.55 A / 125 V DC-13. It ships without positive opening, so it suits general control logic rather than safety-interlock circuits that require a certified positive-break NC contact. Screw-clamp terminals accept 0.22-2.5 mm2 conductors, matching the wiring range used across the 9001K contact-block series, so it stacks directly onto an existing operator body without changing termination hardware.

Applications

Adds a changeover contact to Harmony 9001K and 9001SK 30 mm pushbutton and selector-switch stations for indicator lamps, relay coils, or interlocking circuits in general machine-control panels and operator stations.
