Schneider Electric 9001KA53 No/nc Contact Block

Product Description

The SCHNEIDER ELECTRIC 9001KA53 is a NO/NC dual-contact block designed for use with Harmony 9001K series control devices. It provides both a normally open and a normally closed switching circuit through a single screw-terminal assembly. Rated at 125 VDC at 0.55 amps and 240 VAC at 3 amps, this contact block handles the low- to mid-level current demands typical of industrial control circuits. The screw terminal connection allows for secure, tool-based wiring without soldering. Licensed electricians and industrial controls technicians install this component as a replacement or add-on contact element in pushbutton and selector switch assemblies.

This contact block is intended for use in control panel assemblies, machine operator interfaces, and industrial switching applications where both NO and NC contact states are required in a compact form factor. It is a direct-fit replacement or supplementary contact element for Harmony 9001K series devices, making it a common service part in light manufacturing, process control, and facility electrical systems. Both residential and commercial electricians working on control panels will encounter this part type during maintenance and retrofit work.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the control panel and verify zero voltage with a meter before removing or installing contact blocks. Screw terminals should be tightened with an appropriate flathead screwdriver to ensure a secure connection without over-torquing. Confirm the NO/NC contact orientation matches the control circuit logic before restoring power.
