Schneider Electric 9001KR4R 30 mm red mushroom push button

Industrial control operator

The Schneider Electric 9001KR4R is a 30 mm red mushroom push button built for industrial control panels. Its momentary action suits emergency-stop or start functions where a large, unmistakable actuator is required. The metal head, bezel and base withstand repeated impact in harsh environments. Operators who need a compact, highly visible manual input will find it fits standard 30 mm cut-outs.

Metal construction and sealing

A full-metal mushroom head, bezel and mounting base resist mechanical abuse and corrosion better than plastic alternatives. The 35 mm head diameter gives a clear target for gloved hands while the IP66 rating and NEMA 1, 2, 3, 3R, 4, 12, 13 classifications confirm protection against dust, water jets and oil. Panel mounting is straightforward with the standard 30 mm thread, reducing installation time on new builds or retrofits.

Passive operation and compliance

The device draws no power and generates no heat or noise because it is a purely mechanical contact operator. Contacts are supplied separately, so the electrical rating depends on the chosen block. Compliance with REACH and RoHS ensures the materials meet current substance restrictions for European and global markets. A signaletic sound alarm feature provides audible feedback when the button is actuated.
