Softstarter PSR6-600-11 / 3kW at 400V 1SFA896104R1100

Softstarter – Smooth start for three-phase motors

This softstarter, from the PSR series, is a compact device designed for smooth starting and stopping of three-phase motors. Its main function is to limit inrush currents, which translates to reduced mechanical and electrical stress on the installation. The device is particularly useful in applications where frequent starting and stopping of motors generates high inrush currents.

The PSR6-600-11 softstarter allows for effective control of motors up to 3 kW at 400V. The built-in bypass contactor ensures stable motor operation after the start-up phase, minimizing energy losses. The device is characterized by its versatility – it works with both AC and DC power supplies at 24V.

Design and application

The device has been designed with ease of installation and adjustment in mind. The ability to mount on a DIN rail or directly on a mounting plate makes it suitable for various control cabinet configurations. Compact dimensions allow installation even in limited spaces. The PSR6-600-11 softstarter is an ideal solution for a wide range of industrial and commercial applications, such as:

• Pumps
• Fans
• Compressors
• Conveyors
• Blowers
