Function: M-LB-Ex-5000

The device is the base for the modules of the surge protection system:
- Protection modules
- Place-holder modules
These modules are connected to the device.

The protected and unprotected signal lines are connected to the device. The plugged modules will be grounded via the integrated earth connection.

The terminals of the base module are suitable for the connection of conductors and plug‑in jumpers.

The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
