9001KA1 is a 30 mm Harmony contact-block accessory for Schneider Electric's Harmony 9001K push-button family (Types K, SK or KX). It provides one normally open (NO) and one normally closed (NC) contact, enabling signaling and interlocking in control circuits without replacing the main operator. The block mounts to compatible 30 mm push-buttons and uses screw-clamp terminals for straightforward wiring, with a 600 V AC rating for the contact circuit, and is designed to be used with Harmony 9001K push-buttons and selector switches.
