Softstart PSE18-600-70 1SFA897101R7000

Softstarter – Smooth start and motor protection

This softstarter is a compact solution for the smooth starting and stopping of three-phase motors, minimizing electrical and mechanical stress. The device combines functions of limiting inrush currents, overload protection, and torque control, which translates to a longer motor and installation life. A built-in bypass contactor ensures efficient operation and reduces energy losses.

Versatile application and easy operation

The PSE18-600-70 softstarter is designed to work with motors up to 7.5 kW at 400V and 11 kW at 500V. Equipped with a clear display and intuitive operation, it allows easy monitoring of operating parameters and device configuration. Thanks to the ability to program current limiting and the kick-start function, the softstarter's operation can be adapted to specific application requirements. Additionally, the housing with a PCB coating ensures reliable operation even in harsh environmental conditions.

Functionality for professionals and end-users

The device offers a wide range of functions, such as: protection against overload, rotor lock, underload, as well as the possibility of remote control and monitoring via Modbus RTU communication. A built-in switch allows for quick disconnection of the device if necessary. This makes the PSE18-600-70 softstarter an ideal solution for both installers looking for a reliable and easy-to-install device, and for end-users who value safety and energy efficiency.
