Schneider Electric 9001KA54 Contact Block 2NC 3A

Product Description

The SCHNEIDER ELECTRIC 9001KA54 is a 2NC (normally closed) contact block designed for use with 30mm push button and selector switch operator assemblies in industrial and commercial control panels. Rated at 3 amps with compatibility at 115 volts DC and 240 volts AC, this contact block uses screw terminal connections for secure, reliable wiring. It is a compact add-on or replacement component installed by licensed electricians and industrial maintenance technicians during panel builds, equipment retrofits, or field service calls. The unit fits a 30mm (1.18 inch) mounting hole diameter, which is the standard format across a wide range of operator devices.

This contact block is suited for control panel applications in manufacturing, process control, HVAC equipment control, and machine guarding circuits. It installs onto compatible 30mm push button heads, selector switches, and emergency stop operators to form a complete switching unit. The 2NC configuration makes it a common choice for safety interlock, stop-circuit, and monitoring applications where a closed-to-open signal is required on activation. Maintenance electricians and panel builders will find the screw terminal interface straightforward to wire and inspect.
