Schneider Electric XCSB501 is a Telemecanique Preventa safety interlock switch with a metal housing (zinc alloy) that provides a locking mechanism for guarding access to industrial equipment. It features 2 normally open and 1 normally closed contacts and includes a keyed actuator for secure locking with push-button release. The unit has a single entry tapped for cable routing, and it is designed for gate and door monitoring in safety-control circuits—working with Schneider safety relays to help ensure the machine cannot restart while a guarded access is open.
