Softstarter Uwe=3x400V AC, Iwy=37A, Pmax=18kW SF-180

Soft start for three-phase motors – efficiency and protection

This soft starter, with a rated voltage of 400V AC and an output current of 37A, is key to smooth and safe starting of three-phase asynchronous motors. The device is designed for applications requiring limitation of inrush currents during start-up, which translates to a longer motor life and reduced load on the power supply network. It replaces traditional star-delta starting systems, offering more advanced functions and greater control over the starting process.

Functionality and safety in one device

The SF-180 soft starter is not only a gentle start. It is a comprehensive solution providing motor protection at every stage of operation. Built-in overload protection prevents damage caused by excessive load, and underload protection prevents the motor from malfunctioning. Additionally, the device has overvoltage and undervoltage protection, which increases its reliability in variable network conditions. Thanks to this, you can be sure that the motor runs stably and safely, regardless of the load or power supply conditions.

Control and flexibility for professionals

The device offers full three-phase control and six types of starting characteristics, allowing precise adjustment of parameters to the specifics of the drive. Control of torque, current and power during start-up and operation ensures optimal efficiency and minimizes the risk of failure. The control panel with keyboard and LED display makes configuration and monitoring of operating parameters easier. Analog current control output and programmable relay outputs allow integration of the soft starter with automation systems and remote control. Error memory facilitates troubleshooting, and the ability to automatically restart the motor increases the reliability of the entire system. The rated power of the three-phase motor with standard connection is 18 kW, and the rated ambient temperature is 40°C.
