ABB PFSA 145 3BSE008843R1 Mains Filter

Description

ABB PFSA 145 3BSE008843R1 Mains Filter is an industrial control mains filter designed for precision power management and system protection. This unit delivers core functions including torque transfer control with clutch and braking capabilities, and can replace standard clutches for rapid engagement/disengagement in machine tools, numerical control devices, computers, wide-format printers, and precision positioning machinery. It supports stepless speed regulation when paired with sensors and control circuits, making it ideal for high-speed fine-tuning and small to medium power speed control systems. The filter also provides reliable overload protection: when torque exceeds safe limits, the clutch automatically slips to safeguard machinery and prime movers, and it enables no-load starting of prime movers with gradual loading to boost equipment load capacity. Optimized for constant tension control systems, it is widely used in printing machines, slitting machines, laminating machines, coating machines, paper machines, wire drawing machines, cable winding machines, as well as metal sheet/tape, film processing equipment, and textile machinery. It also serves as an overload protector in mining hoists, cranes, and cement, steel production machinery, ensuring stable, efficient operation in demanding industrial environments.
