Soft starters are static motor control devices designed to accelerate, decelerate, and protect three-phase induction motors by controlling the applied voltage. Unlike traditional star-delta or direct-on-line starters, these units eliminate mechanical shock and electrical stress during startup. They incorporate advanced power electronics and software to regulate voltage and current at boot time, offering smooth torque control and reduced inrush current. Key technical parameters include rated operational current (e.g., up to 1050 A), rated voltage (up to 690 V AC), and protection features like overload, phase loss, and over-temperature. They are available in various frame sizes for panel or standalone mounting.
These devices are deployed in industrial environments where controlled motor starting is critical, such as conveyor systems, pumps, fans, compressors, and mixers. They are commonly installed in distribution panels, motor control centers (MCCs), and automation cabinets. Their ability to reduce mechanical wear and electrical disturbances makes them ideal for applications requiring frequent starts or soft stopping, like in water treatment plants, HVAC systems, and material handling.
The category includes subcategories like the ABB PSR series (e.g., PSR3-600-70, PSR6-600-70) for standard applications, the PSE series (e.g., PSE18-600-70, PSE30-600-70) with built-in bypass, and the PST/PSTB series (e.g., PST30-600-70, PSTB50-600-70) for heavy-duty use. Article codes typically follow a pattern like [Series][Current Rating]-[Voltage]-[Control Voltage], e.g., PSR3-600-70 indicates a PSR soft starter rated for 3 A at 600 V with 70 V control.
