Terminal connection module,terminal connection block ,
1 Pair Subscriber Terminal Box
Description
The module of the connection of family VX is intended for the joint between the cable pair based on the side of commutation station and the distributive pair.
It is 5- polar insertable module for provision of through connection and guarantee of a number of other different functions.
The end fitting of wires is not disrupted with turning off of insertable module, but is ensured the possibility of testing cable system beside any of both sides.
The module of connection is established beyond the longitudinal tire, made from the stainless steel, which corresponds to standard DIN. Module can be established beside different types of housings, before different quantities. Compactness ensures the small size of base to article (with width only of 2 cm).
