Pepperl+Fuchs offers high-end surge protection with M-LB-5000

Published on : Tuesday 30-11--0001

The patented diagnostics of the M-LB-5000 with its intuitive and easy-to-read traffic-light display minimises testing costs in accordance with EN 62305-3 and allows condition monitoring. The green light on the protection module indicates that there is full protection and sufficient operating reserve. The yellow LED indicates that the protection module has reached 90 % of its lifecycle, but the signal circuit is still protected. The protection module should be replaced when maintenance is next performed. If the indicator is red, the protection module is permanently damaged and protection has been lost. The protection module should be replaced immediately to prevent damage during the next overvoltage condition.

This setup ensures that the protection modules are always replaced at the ideal time. This improves the availability of the surge protection, and therefore of the system as a whole, and at the same time minimises maintenance costs. The status of the protection modules can be integrated into the control level via the signalling contacts of the function modules and via the Power Rail.

At 6.2 mm, the small width of the protection modules saves space in the switch cabinet. Disconnect terminal blocks can be avoided: During retrofitting, existing common disconnect terminal blocks can be replaced regardless of space requirements.
