Softstarter TSA52070 UMAX 525V IMAX 70A

Intelligent motor starters – softstarter EATON DS7 TSA52070

This softstarter, designated TSA52070, is an advanced device used for smooth motor starting of three-phase motors. Designed to operate in 400-525V networks, it allows for effective limitation of starting currents and minimization of mechanical stresses in the drive. This is crucial for extending the life of the motor and connected components. The device finds application in a wide spectrum of industrial applications where torque control and motor protection against overloads are required.

Functionality and application

The TSA52070 softstarter is not only a starting current limiter. The built-in contactor (bypass) ensures reliable switching to full power after the starting process is completed, minimizing power losses in the circuit. Torque adjustment allows you to adapt the starting characteristics to the specific requirements of the application – from gentle starting for pumps and fans to more dynamic starting for compressors and conveyors. The reverse starting function expands the possibilities of using the device in applications requiring frequent changes in the direction of rotation. Integrated motor overload protection protects it from damage in the event of an overload or short circuit. The display facilitates configuration and monitoring of the device's operating parameters.

Key features and benefits

• Motor and installation protection: Rated operating current of 70A at an ambient temperature of 40°C and tripping class 10 ensure effective protection against overloads and short circuits.
• Starting process control: Torque adjustment allows precise adaptation of the starting characteristics to the needs of the application, reducing hydraulic shocks in pumps or mechanical stresses in gearboxes.
• Versatility: The ability to power the control voltage with AC/DC 100-240V ensures compatibility with various control systems.
• High efficiency: The built-in bypass contactor minimizes power losses during operation at full engine speed.
• Easy operation: The display enables quick configuration and monitoring of device parameters, and the IP20 protection class ensures safe use in industrial conditions.
• Wide power range: Supporting motors up to 37 kW (at 400V) makes it a universal solution for many applications.
• Additional functions: In addition to standard functions, the softstarter offers logic functions and JOG speed mode, which increases its flexibility and possibilities of use.

The EATON DS7 TSA52070 softstarter is a solid and reliable device that significantly improves energy efficiency and extends the life of electric motors. It is an investment that quickly pays for itself thanks to reduced operating costs and minimized downtime related to failures.
