Overview
The Square D 9001 KR1U is a universal push button operator designed for industrial control applications requiring robust, reliable switching in demanding environments. Part of the Schneider Electric Harmony 9001K series, this 30mm push button features a chromium-plated metal bezel and full guard design that protects the operator from accidental actuation while maintaining accessibility for routine operation.
Key Features
- Automatic Self-Grounding: Requires no additional ground wires, reducing wiring complexity and installation time

Typical Applications
30mm push buttons are used in automotive, machine tool, crane and hoist, food and beverage, industrial applications, material handling, petrochemical, wastewater treatment, metallurgy and many more industries. The 9001 KR1U is ideal for:
- Heavy machinery start/stop control
- Conveyor and process automation systems
- Outdoor or wet-environment installations
- Equipment requiring washdown or chemical exposure protection
- Hazardous or corrosive industrial locations
Compatibility & Replacements
The Square D 9001 KR1U is part of the Harmony 9001K modular series and is fully interchangeable with other 9001K operators using standard 30mm mounting. It accepts a full range of contact blocks, colored inserts, and pilot light modules. This push button operator is a direct replacement for legacy Square D Type K pushbutton systems and maintains backward compatibility with existing 9001K installations. For applications requiring corrosion resistance, consider the 9001SK variant with black plastic bezels; for multi-function operation, the 9001KX square bezel option is available.
