Cutler-Hammer C320KA1 Auxiliary Contact Block

Cutler-Hammer C320KA1 auxiliary contact block provides a single normally open auxiliary contact rated for up to 600V. This device adds an auxiliary signaling contact to control circuits, enabling status indication or interlock logic without carrying the main load current. The part number C320KA1 uniquely identifies this unit in Cutler-Hammer's line of auxiliary contact accessories. With a 1NO configuration, the block delivers a dry contact output that can be used for feedback to control systems, signaling relays, or other logic in electrical panels and motor control applications. Used in electrical panels and control installations where a separate, isolated signaling path is desired, it supports straightforward integration into automation architectures that rely on independent contact closures for monitoring and control purposes.
