Schneider Electric 9001KA43 Contact Block No/nc

Product Description

The SCHNEIDER ELECTRIC 9001KA43 is a NO/NC contact block designed for use with Harmony 9001K pushbutton and selector switch assemblies. It provides both a normally open and normally closed contact in a single compact unit, allowing control circuit switching at 125 VDC at 0.55 amps and 240 VAC at 3 amps. Connections are made via screw terminals for a secure, serviceable wiring interface. Licensed electricians and industrial control panel builders install this block as part of operator interface stations in machine control and process automation applications. The unit weighs 0.09 pounds and measures 1.7 inches by 1.9 inches by 1.2 inches.

This contact block is suited for residential, commercial, and light industrial control panel work wherever Harmony 9001K operator devices are installed. Typical applications include pushbutton stations, selector switches, and emergency stop assemblies on control panels, motor starters, and machine interlocks. It is a direct add-on or replacement block that snaps onto compatible 9001K operator bodies to restore or expand switching logic in existing or new installations.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements for control panel wiring. De-energize and lockout/tagout the control panel before removing or installing contact blocks. Verify screw terminal torque meets the panel builder's or enclosure manufacturer's specifications before returning equipment to service. Do not exceed the rated voltage and current values for the contact circuit being switched.
