The distribution components of the 71 Series have basically the same structure as those of the 71 Series.
They offer the following features:
• 4- or 5-pair organization • Contact wire Ø 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 Application Options The classic area of application of the 71 Series distribution system is the main distribution frame.
