Schneider Electric 73350 Electrical Interlock

Schneider Electric's 73350 electrical interlock, part of the Square D family, is a safety-oriented interlock component designed to work with compatible enclosure doors and actuators in electrical distribution equipment. The part number 73350 identifies this specific interlock unit in Schneider Electric's catalog. Used to coordinate the position of a door or access point with the equipment's control circuit, it helps ensure that a device cannot be operated or accessed while the enclosure is not in a safe state. This interlock is a standalone device intended to be paired with the corresponding actuator and mounting hardware within standard Square D enclosure and switchgear configurations, making it suitable for industrial and commercial electrical installations requiring controlled access to live equipment. When selecting replacements or upgrades, reference the 73350 designation to confirm mounting pattern and interface with your enclosure's interlock mechanism and actuator to maintain proper safety interlock sequencing.
