Product Positioning
The SIRIUS 3SE5322-0SD21 is a Siemens spring-locking safety interlock switch that automatically locks upon power failure. The front panel is equipped with a manual auxiliary release device for easy manual unlocking in emergencies. The switch itself does not contain an actuator.
Core Product Advantages and Features
Spring locking mechanism
The locking force is generated by spring force, and the locking state is automatically maintained when the power is off, which complies with the safety principle of power failure protection and improves the safety of the protective door.
Front panel manual assisted release
The panel is equipped with a manual release device, which allows the safety door to be unlocked manually in case of power failure or emergency, balancing safety and convenience.
24VDC electromagnet release
It requires 24VDC power to release the lock, making it suitable for high-security protective door applications that require locking upon power failure.
Multi-voltage contact rating
The contact ratings cover 24/240VAC and 24/125/250VDC, with a current of 0.27~6A, and can be flexibly matched with different control circuits.
