Contactors
The VS65 SS with a rated current <400A is equipped with a line vacuum contactor and a bypass
vacuum contactor, both are selected according to the rated voltage and the configuration
(removable or fix). The contactors enables to performance the starting and stopping sequence,
and to interrupt the supply under normal conditions. The following table summarizes the
characteristics.

General Protections
The VS65 integrate as standard multiple protections such us phase sequence, overload,
underload, shearpin current, PTC signal, start limits, and other. Further information about
functional operation and configuration can be found in Software and Programming manual.

Wiring Access
The following figures show the access to the VS65 soft starter power terminals to connect the input
power supply and the motor output cables, which is found in the back part of the equipment. As shown in
the images below, in the bottom part we find the plate with the necessary cable pass.
