Frequently asked questions

What does 'defeatable' mean for the Siemens 3LD2517-1TL13 emergency switch?

The 'defeatable' feature means the emergency stop function can be reset by turning the knob (often after pulling it out), allowing for a controlled re-energization after the condition that triggered the emergency stop has been resolved. This differs from non-defeatable types that may require a key or different action to reset.
