Frequently asked questions

What does 'door coupling' mean for the Siemens 3LD2113-0TK51?

Door coupling on the Siemens 3LD2113-0TK51 allows the switch to be operated from outside an enclosure, typically via a rotary handle mounted on the enclosure door. This provides safe external control of the internal disconnector without needing to open the enclosure.
