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



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

1. Central offices

2. Customer premises, e.g.

- Company networks

- Universities

- Hospitals

3. Made of ABS

4. Flame retardant

5. Special tool steel(high speed steel) with solid performance

6. For Siemens 71series terminal block termination, blue and grey

7. Cuts excess wire in one click operation

8. Ensures proper insertion of wire
