Modules for DIN rail

DIN rail-mounted surge protection modules for signal lines are available in three versions:

M-LB-4000, the latest surge protection module, consists of a base module and a protection module that can be changed without tools if necessary. With a width of only 6 mm, M-LB-4000 reduces space requirements to a minimum. A Loop Disconnect function is made possible by plugging-in the protection module through 180 degrees. The clearly visible status display on the front of the protection modules immediately detects any fault status. 

M-LB-2000 is a simple and cost-effective surge protection in a compact package. It is 6.2 mm wide and fits easily into any standard environment, and it also offers the Loop Disconnect function via two easily accessible switches. It is easy to mount and requires no tools. 

With the 12.5 mm wide modules of the K-LB series, 3- and 4-wire applications can be realized with only one device.
