Pepperl+Fuchs M-LB-4000 surge protection system

Click2Contact

The modular design of the Pepperl+Fuchs M-LB-4000 system allows users to quickly exchange pluggable surge protection modules during operation without any interruption of the signal circuit. The entire protection function is housed in the protection module. If the protection module is removed and re-inserted with 180° rotation, the signal circuit is interrupted by the integrated disconnect function. This loop disconnect feature allows isolation testing as well as loop monitoring during commissioning.

With a width of 6 mm, the M-LB-4000 surge protection modules provide a high packing density and reduce installation space to a minimum. User-friendly mechanics allow operational staff to install the modules without any additional wiring effort. The M-LB-4000 also offers self-monitoring: the display shows status information that can also be forwarded to the control level with a fault status indication module, simplifying maintenance and reducing operational costs.
