Schneider Electric XCSL749F3 Safety Interlock Switch

Schneider Electric XCSL749F3 Safety Interlock Switch is a metal-bodied guard interlock from the Telemecanique Sensors / Schneider Electric Preventa XCSL series that uses a key-operated actuator with solenoid locking and positive-opening safety contacts to prevent machine start-up until the guard is closed and locked. It is designed for guarding machine access doors, safety gates, protective enclosures, robotic cells, and packaging machinery, and integrates with safety relays and controllers in industrial safety circuits. Key specifications include a 110 V AC solenoid supply, 3 A at 240 V AC operating current, a 2 NC + 1 NO contact configuration, slow break and break-before-make operation, screw-clamp terminals, a metal enclosure, and IP67 protection. Common replacements for compatibility include XCSLF3737333, XCSE7313, and XCSLE.
