Conductor Pull-Out Forces
The clamping units screwless terminal
blocks must withstand the pull-out forces as
follows:

. For example, the pull-
ing force for conductor having cross section 1. During the test, the
conductor must neither slip out the clamping unit, nor break near the clamping unit. The pulling force selected according
to the cross-sectional area.6

During the test, pulling force applied without jerking, for one minute, the connected conductor.

Table 2:
Safety requirements for screw-clamp and
screwless clamping units for electrical cop-
per conductors
The pull-out test simulates the mechanical stress the clamping unit when, for example, the installer pushes the conductor aside better
access/operate the adjacent clamping unit, verifies the conductor connected properly briefly pulling it.5
0. The larger the cross section the conductor, the higher the pull-out force that selected.wago.5
