Efficient Motor Control with ABB PSTX Softstarters
Bypass contactors are used with softstarters to allow efficient motor operation after the acceleration phase. Once the motor reaches normal operating speed, the bypass contactor closes to transfer the motor supply path away from the softstarter power electronics, reducing losses during continuous operation.
The ABB PSBP-750 provides a practical solution for engineers designing or maintaining PSTX-based motor control systems where reliable bypass switching and long-term operational efficiency are required.
Typical Applications
- Industrial motor control systems.
- ABB PSTX softstarter installations.
- Pumps and compressors.
- Fans and ventilation systems.
- Heavy-duty machinery.
- Process automation equipment.
