Description

The PSTX720-600-70 softstarter is an advanced motor control and protection solution designed for medium to large industrial motors. It provides precise three-phase control for smooth motor acceleration and deceleration using a voltage or torque ramp, reducing mechanical stress and electrical surges. With a rated operational current of 720 A and voltage range of 208–600 V AC, it ensures stable and energy-efficient operation in demanding environments.

This soft starter integrates a built-in bypass for easy installation and reduced energy consumption, along with advanced protection features such as current limit, EOL, motor heating, and pump cleaning. It includes diagnostic and sequence start functions, making it ideal for dynamic industrial systems. The PSTX720 supports Modbus RTU and optional ANYBUS modules compatible with major communication protocols like Profinet, Profibus, Modbus TCP, and Ethernet/IP. Its detachable IP66-rated display allows full control and monitoring even in harsh conditions. For optimized electrical design, it can be integrated with our industrial panel fabrication services for complete system efficiency.
