LSA Module Series


The distribution components of the 71 Series  have basically the same structure as the 5000  Series. They offer the following features:

 ● 4- or 5-pair organization

 ● Contact wire Φ from 0.4 to 0.8 mm

 ● 3-point protection can be plugged in from the   rear IDC contacts accessible when protection   is plugged in

Overvoltage Protection Magazine (3-point protection)  with 2-Electrode 

Arrester and Hot Melt


The overvoltage protection  magazines of the 71 Series are  fitted with 2- or 3-electrode  arrestres . The protection  magazines can be supplied with or  without a ground short-circuit  spring or hot melt.


 The classic area of application of the 71 Series distribution system is the main distribution  frame. The MDF is used in, for example:

● Central offices 

● Customer premises, e.g. 

●Company networks

● Universities
