DESCRIZIONE PRODOTTO
SCHNEIDER ELECTRIC CA4KN40FW3 - Auxiliary Contact Block
This device is a front-mounted auxiliary contact block from the SCHNEIDER ELECTRIC TeSys K series, designed for integration with TeSys K miniature contactors. It provides four normally open (NO) auxiliary contacts, expanding the signaling and control capabilities of the main contactor. This component is critical for implementing complex interlocking, status indication, and control logic within industrial automation systems, motor control centers, and machinery control panels.
