Schneider Electric 9001SKS42B 3-position Selector Switch

Product Description

The SCHNEIDER ELECTRIC 9001SKS42B is a 3-position maintained selector switch operator designed for industrial and commercial control panel applications. This unit features a black knob-style operator with a plastic bezel and mounts through a standard 30 mm panel cutout. The maintained (MA) operation type means the switch holds its selected position until physically moved, making it suitable for mode-selection and on/off/off circuit control tasks. The 9001SKS42B ships as the operator only, with no contact blocks included. It carries UL, CSA, and CE certifications and is rated for NEMA 1, 2, 3, 3R, 4, 4X, 6, 12, and 13 enclosure environments, covering everything from indoor dry locations to outdoor and corrosive-atmosphere installations.

This selector switch operator is used in residential, commercial, and light industrial control panels where a durable, multi-position selector is needed for equipment mode selection, circuit switching, or machine control. The anti-corrosive, dust-resistant, oil-resistant, and weatherproof resistance ratings make it appropriate for demanding environments including manufacturing floors, pump panels, outdoor enclosures, and wash-down areas. Licensed electricians and industrial control technicians are the typical installers. No contact blocks are included and must be sourced separately to complete a functional switch assembly.

Compatibility

Designed as an OEM-style panel-mount selector switch operator for 30 mm industrial control stations. Compatible with control enclosures rated NEMA 1, 2, 3, 3R, 4, 4X, 6, 12, and 13. Contact blocks must be added separately and are not included with this operator.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the control panel before mounting or wiring any switch operator. The 30 mm panel cutout must be clean and free of burrs to ensure proper seating and NEMA-rated sealing. Because this unit ships without contact blocks, verify contact block selection and wiring configuration before commissioning the assembly.
