ABB PSBP-750 1SFA899301R1750 bypass contactor designed for ABB PSTX softstarters in industrial motor control applications.
£8,480.32
The ABB PSBP-750 1SFA899301R1750 is a dedicated bypass contactor designed for use with ABB PSTX softstarters in industrial motor control applications. As part of the ABB PSTX softstarter accessory range, it provides reliable bypass switching to improve system efficiency by allowing motors to run directly from the supply once the soft start sequence has completed.
This bypass contactor is engineered specifically for ABB PSTX softstarter systems, providing a robust switching solution for high-power motor applications. Its three-pole construction, industrial-grade design and compatibility with PSTX installations make it suitable for demanding automation and process control environments.
With a compact assembly measuring approximately 210 × 240 × 282 mm and a weight of approximately 13.934 kg, the PSBP-750 provides a complete bypass switching solution for compatible ABB PSTX softstarter installations.
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.
