Softstart PSTX370-600-70 1SFA898115R7000

Advanced motor starter – PSTX370-600-70

This ABB PSTX series advanced softstarter is a reliable solution for smooth starting and stopping of three-phase motors. The device not only limits electrical and mechanical loads but also provides complete motor protection, extending its lifespan. The use of coated printed circuit boards makes it resistant to operation in harsh conditions, in an aggressive chemical environment.

PSTX370-600-70 stands out for its ability to adjust the torque, allowing for optimization of the starting process for various types of loads. The built-in bypass contactor ensures continuous operation after the start-up is completed, minimizing energy losses. Additionally, the device has a built-in motor overload protection, protecting it from damage. A removable control panel facilitates operation and maintenance.

Functionality and application

The PSTX370-600-70 softstarter is designed to work with motors with a supply voltage of 208…600 V AC and a rated current of 370 A. It can be used in a wide range of industrial applications, such as pumps, fans, compressors, conveyor belts, and mixers. Thanks to the reverse starting function, it is ideal for applications requiring frequent changes in direction of rotation. The built-in graphic display makes configuration and monitoring of device parameters easier. Modbus RTU communication enables integration with automation and control systems.

Key features and benefits:
