The aim of the soft starter is to minimize the high inrush current during the start of a 3ph squirrel cage motor. This protects the electric supply and electric installation from overload.

In plants with multiple motors, the use of a soft starter reduces the dimension of wires sizes, protection systems and supply maximum power.

Due to its highly integrated functions and protection circuits of the Christian P-4.0/RL/TP/IC you do not need to install the classic motor protection. The installation requires only the line fuses to protect the wires.
