Description

The PSTX1250-600-70 softstarter delivers advanced motor control for high-power industrial applications. Designed for smooth start and stop performance, it operates within a wide voltage range of 208–600 V AC and supports up to 1250 A. This three-phase controlled unit provides ramp-up and ramp-down through either voltage or torque control, ensuring optimal torque management and reduced mechanical stress on equipment. With a built-in bypass, installation is simplified and power losses are minimized.

It also includes extensive protection and control features such as current limiting, EOL, motor heating, and pump cleaning. The PSTX1250 supports Modbus RTU communication and optional ANYBUS modules compatible with Profinet, Profibus, Modbus TCP, and Ethernet/IP. The detachable IP66 graphic display allows intuitive setup and monitoring, even in harsh industrial conditions. For complete integration and wiring optimization, use it within our industrial panel fabrication solutions.
