Motor Soft Starter – Optimization and Protection

Soft starter PSE45-600-70 is an advanced device designed for smooth starting and stopping of three-phase motors. Using a soft starter allows you to limit inrush currents, reduce mechanical stress, and extend the life of the motor and connected installation elements. The device finds application in a wide range of industrial and commercial applications where control of the starting process and protection against overloads are required.

Functionality and Construction

PSE45-600-70 features a built-in bypass contactor, which ensures efficient heat dissipation and minimizes energy losses during stable operation. It also has a built-in motor overload protection, protecting it from damage caused by excessive load. Adjustable torque allows you to adapt the starting characteristics to the specifics of the device, and the display facilitates configuration and monitoring of operating parameters. Control is via an AC signal with a voltage of 100-250V.

Applications and Benefits

This soft starter is an ideal solution for motors up to 22 kW with a standard 400V connection or 18.5 kW with a star connection. It can also be used with motors powered by 208...600 V AC. Using PSE45-600-70 translates to:

• Reduction of inrush currents: Limiting shock starting currents reduces the load on the power supply network and minimizes the risk of overvoltage.
• Extended motor life: Smooth starting reduces mechanical stress on the motor, resulting in longer operation.
• Protection against overloads: Built-in overload protection protects the motor from damage caused by excessive load.
• Easy configuration: The display makes it easy to read operating parameters and adapt the device to specific application needs.
• Versatility: Adjustable torque allows for optimization of the starting process for different types of loads.
• Built-in bypass contactor: Ensures efficient heat dissipation and minimizes energy losses in a stable state.
• Wide range of supply voltages: The device can operate in networks with a voltage of 208 to 600 V AC, which increases its versatility.

Additionally, the soft starter has a kick-start function and programmable current limitation, allowing for even more precise adaptation to specific application requirements. The PCBs are coated, providing resistance to operation in harsh industrial environments.
