PSTX softstarter

The advanced range ~ The PSTX comes to the market fully loaded. The PSTX is ABB’s latest advancement in motor control and protection and adds new functionality with increased reliability to any motor starting application. ABB’s softstarters increase a motor’s lifetime by protecting it from electrical stresses. They do so by letting you optimize starting currents that with conventional starting methods put lots of stress on the motor. With many built-in motor protection features, your motor is safe in its hands.

PSTX2016The ABB PSTX Softstarter family helps you use your process to its fullest potential. Many features like torque control, jog with slow speed and pump cleaning were designed to deal with specific problems that may occur when using conventional starting methods. The PSTX helps both your motor and application do more.

The PSTX offers complete motor protection in only one unit and is able to handle both load and network irregularities. PT-100, earth fault protection and over/under voltage protection along with many other functions keep your motor running even through the roughest of networks.

Built-in bypass saves time and energy When reaching full speed, the PSTX will activate its bypass. This saves energy while reducing the softstarter’s heat generation.On the PSTX, the bypass is built in and verified by ABB, saving you time during installation and space in your panel.
