Spring-cage technology

Spring-cage technology enables easy connection without the need for special tools and conductor pretreatment.


This spring is opened via the actuation shaft using a screwdriver and the conductor is inserted into the spring-cage via the separate conductor shaft.

When the tool is removed, the spring then pulls the conductor against the power rail. This connection can be released in the same way.
