Softstarter TSA52042 UMAX 525V IMAX 42A

Intelligent motor starters with Emotron TSA52042

The Emotron TSA52042 softstarter is an advanced device designed for smooth starting of three-phase motors. It not only limits starting currents but also offers a range of functions to increase the efficiency and reliability of the installation. This solution is ideal for both professional installers and end-users looking to optimize the motor starting process.

Functionality and application

The TSA52042 device is characterized by a wide range of supply voltage (400…525 V) and rated current of 42A, allowing it to be used in various industrial applications. The built-in bypass contactor minimizes power losses after starting, and the adjustable torque allows precise adjustment of parameters to the specifics of the load. The reverse starting function expands the range of applications to include those requiring a change in motor rotation direction.

Using the TSA52042 softstarter translates into a number of benefits:

• Reduction of mechanical stress: Smooth starting reduces hydraulic and mechanical shocks in gearboxes, pumps and other elements driven by the motor, extending their service life.
• Limitation of starting currents: Reducing peak currents during motor starting relieves the power supply network and avoids voltage drops affecting the operation of other devices.
• Torque control: Precise torque adjustment provides optimal starting conditions for different types of loads.
• Built-in protection: Motor overload protection protects it from damage in the event of overload or short circuit.
• Easy operation and diagnostics: Equipped with a display to facilitate configuration and monitoring of device operating parameters.

Design and parameters

The TSA52042 softstarter has been designed with reliability and durability in mind. The IP20 protection class provides protection against contact, and the release CLASS 10 guarantees a quick response in the event of a failure. The device operates at an ambient temperature of up to 55°C, allowing it to be mounted in harsh industrial conditions. Compact dimensions (detailed data available in the technical documentation) make it easy to integrate with existing infrastructure. The AC control voltage (100…240 V) ensures compatibility with most control systems. Additional logic functions and JOG mode increase the flexibility of the device and allow it to be adapted to specific application needs.
