Schneider Electric 9001KA42 Nc Contact Block Screw Terminal

Product Description

The SCHNEIDER ELECTRIC 9001KA42 is a normally closed (NC) contact block designed for use with Harmony 9001K series pushbutton and selector switch operator assemblies. It provides electrical switching at 125 VDC at 0.55 amps and 240 VAC at 3 amps, with screw terminal connections for reliable field wiring. This block mounts directly to a compatible operator body to complete the switch assembly in control panel and machine control applications. Electricians and panel builders install this component when building or servicing industrial control stations that require NC switching logic.

This contact block is used in light industrial and commercial control panel applications where Harmony 9001K series operators are installed. Common scenarios include operator interface stations, motor control panels, and machine safety circuits requiring a normally closed switching element. The screw terminal design simplifies wiring during panel assembly or field replacement of a worn or failed contact block.

Compatibility

Designed for use with the Schneider Electric Harmony 9001K series pushbutton and selector switch operator assemblies.

Installation Notes

Installation is typically performed by a licensed electrician or qualified control panel builder. De-energize and lock out the control panel before removing or installing any contact block in accordance with NFPA 70E electrical safety requirements. Ensure screw terminals are tightened to the conductor securely and that wire gauge is appropriate for the rated current of the circuit. Do not exceed the rated voltage or current values specified for this contact block.
