Schneider Electric 9001KA52 Nc Contact Block

Product Description

The SCHNEIDER ELECTRIC 9001KA52 is a normally closed (NC) contact block designed for use in industrial control and switching applications. It provides reliable circuit interruption at multiple amperage levels: 0.55 amps at 125 volts DC and 3 amps at 240 volts AC. Connections are made via screw terminals, which accept field wiring without requiring specialized tooling. Electricians and control panel technicians install this contact block as part of operator interface assemblies, where it serves as an auxiliary or primary switching element in machine control circuits.

This contact block is intended for use with the Harmony 9001K series of operator control devices, including push buttons, selector switches, and related control station components. It is suited for light industrial and commercial control panel applications where a normally closed switching function is required. The screw terminal design allows for straightforward field installation and wire termination in standard enclosure and control station assemblies.

Key Features

• Normally closed (NC) contact configuration for fail-safe circuit design
• Dual amperage ratings: 0.55A at 125 VDC and 3A at 240 VAC
• Screw terminal connections for reliable, tool-accessible field wiring
• Compact form factor at 1.8 x 1.7 x 1.2 inches for tight panel installations
• Meets multiple international and domestic standards including UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and RoHS compliance

Compatibility

Designed for use with the Harmony 9001K series of operator control devices from Schneider Electric.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC guidelines and any applicable local codes. De-energize and lock out the control circuit before removing or installing any contact block. Ensure screw terminal connections are tightened securely and that conductors are properly stripped and seated before restoring power. Verify the contact block configuration (NC) matches the intended circuit logic before commissioning.
