Frequently asked questions

What is the purpose of the guard lock feature on the Siemens 3SE5322-0SE21 safety switch?

The guard lock feature on the Siemens 3SE5322-0SE21 safety switch ensures that a machine guard remains physically locked during hazardous operations. The 24V DC lock magnet holds the guard closed, preventing access until the machine is in a safe state and the magnet is de-energized.
