Softstarter TSA52085 UMAX 525V IMAX 85A

Emotron TSA52085 Softstarter – smooth motor starting, protection and control

Emotron TSA52085 softstarter is an advanced device designed for the controlled start-up of three-phase motors. It provides limitation of inrush currents, reduction of mechanical stress and extension of the service life of connected motors and equipment. Thanks to the built-in bypass, it is possible to maintain full current throughput after the start-up process is completed, which minimizes power losses. The device finds application in a wide spectrum of industrial applications, from pumps and fans to conveyors and mixers.

Functionality and application

This model of softstarter, with a rated operating voltage in the range of 400…525 V and a current of 85 A, is ideal for motors up to 45 kW. The built-in motor overload protection protects it from damage caused by excessive load. The ability to adjust the starting torque allows for optimization of the start-up process for different types of loads. The reverse start function allows changing the direction of motor rotation, which is useful in applications requiring frequent changes in the direction of operation. Equipped with a display to facilitate configuration and monitoring of operating parameters.

Advantages and characteristic features

• Torque control: Precise torque regulation ensures smooth and controlled start-up, minimizing hydraulic shocks in pumps or mechanical stress in gearboxes.
• Built-in bypass: Ensures continuous motor operation at full efficiency after the start-up phase is completed, eliminating power losses on the softstarter elements.
• Overload protection: Protects the motor from damage caused by overload, increasing its reliability and service life.
• Reverse start function: Allows changing the direction of motor rotation, which is crucial in some industrial applications.
• Display: Facilitates configuration, monitoring of operating parameters and diagnostics of any problems.
• Wide control voltage range: The ability to power the control from a range of 100…240 V AC ensures compatibility with various control systems.
• Compact dimensions: Allows mounting in limited spaces.
• Protection class IP20: Provides basic protection against touch and access to internal components.
• Release class 10: Ensures a quick response to overloads and short circuits, protecting the electrical installation.

This softstarter is not only motor protection – it is an investment in the reliability of the entire drive system and optimization of industrial processes.
