£395.07
The ABB 1SFA899201R1120 is a genuine PSBP-120 bypass relay designed for ABB PSE softstarter systems. As part of the ABB PSE softstarter accessory range, it provides reliable bypass switching functionality after the motor starting sequence, allowing the softstarter semiconductors to be bypassed during normal motor operation.
This bypass relay accessory helps improve softstarter efficiency by transferring current through the bypass circuit once the motor has reached full speed. The PSBP-120 is designed for integration with ABB PSE softstarters and provides a compact replacement solution for maintenance, repair and system upgrades.
Designed for ABB PSE18–PSE105 softstarters, the PSBP-120 bypass relay offers dependable switching performance in industrial motor control applications including pumps, fans, conveyors and machinery systems. Its compact construction makes it suitable for installation within modern industrial control environments.
Bypass relays such as the ABB PSBP-120 allow softstarters to operate efficiently by transferring motor current through the bypass circuit once acceleration is complete. This reduces heat generation and power losses during continuous motor operation.
The ABB PSE softstarter accessory range provides purpose-built replacement components for industrial motor control systems. Using genuine ABB accessories helps maintain correct operation, compatibility and long-term reliability of softstarter installations.
