The ABB PSR45-600-70 is a compact and reliable soft starter from ABB's well-regarded PSR series. Designed for simplicity and efficiency, it provides essential soft start and soft stop functions, making it an ideal solution for applications that require frequent starting and where space is a constraint. This model is engineered to protect motors and connected mechanical equipment by smoothly ramping up voltage, thereby reducing mechanical stress and inrush current during startup.

The PSR series is the "compact range" in ABB's soft starter portfolio, offering a cost-effective and user-friendly solution for a wide range of industrial applications.

Key Features & Benefits

• Compact Design: Its small footprint makes it perfect for use in space-limited control panels and environments.
• Simplified Operation: Features a graphical display with 4 control buttons, making setup, monitoring, and parameter adjustment intuitive and straightforward.
• Essential Functionality: Provides core soft start and soft stop capabilities to ensure smooth motor acceleration and deceleration.
• High Starting Frequency: Designed to handle multiple starts per hour, making it suitable for demanding applications.
• Built-in Bypass Contactor: Includes an integrated bypass contactor that takes over once the motor reaches full speed. This reduces energy consumption and heat dissipation in the soft starter, extending its operational life.
• Enhanced Motor Protection: Helps prevent issues like water hammer in pumps, belt slippage in fans, and mechanical stress on gears and conveyors, thereby reducing maintenance costs and downtime.
• Coated Control Board Option: For use in harsh environments, versions with a coated control board are available to protect against corrosion from moisture, dust, and chemical agents.
