Description:

ABB PST105-600-70 Soft Starter, order code 1SFA894009R7000, is a standalone three-phase soft starter designed to limit inrush current when starting motors. It is configured for operation with voltages up to 600 V AC and is rated for up to approximately 70 A, enabling a controlled ramp start that reduces torque transients and electrical disturbances on the supply network. This makes it a practical choice for fans, pumps, conveyors, and other equipment in HVAC, process, and general industrial applications where smoother motor starting improves reliability and equipment life. As part of ABB’s PST soft-starter family, the PST105-600-70 provides a compact, panel-mount solution that can replace direct-on-line starts for compatible motors, offering a straightforward, cost-efficient alternative to a full variable-frequency drive when full speed control isn’t required. The 1SFA894009R7000 designation identifies this specific PST105-600-70 configuration within ABB’s low-voltage soft-start lineup, aligning with common industrial needs for reliable, controlled motor starts in space-constrained control panels.
