## Summary description

The Eaton DS7-342SX081N0-N is a high-performance 3-phase soft starter designed for smooth motor starting and stopping. It operates at 400VAC with a rated current of 81A and a power capacity of 45kW. Featuring a control voltage of 110/230VAC, this device reduces mechanical stress and electrical surges in industrial motor applications, ensuring reliable operation and extended equipment lifespan in various automation systems.

## Long description

The Eaton DS7-342SX081N0-N is a robust 3-phase soft starter engineered to provide controlled acceleration and deceleration for industrial electric motors. By managing the voltage supplied to the motor during startup, this device effectively eliminates mechanical shocks and reduces high inrush currents that can damage power grids and drive components. With a rated operational current of 81A and a power capacity of 45kW at 400VAC, it serves as a reliable solution for demanding automation environments.
Advantages
This soft starter offers significant benefits for industrial machinery by ensuring smooth transitions during motor operation. The integration of advanced power electronics allows for precise control over the starting torque, which minimizes wear on belts, gears, and couplings. By preventing sudden electrical surges, the device helps maintain the stability of the local power supply and reduces the thermal stress on motor windings, ultimately contributing to a longer service life and lower maintenance requirements for the entire drive system.
Suitable for
Conveyor belt systems
Industrial pumps and ventilation fans
Compressors and hydraulic power units
Centrifugal machinery
This device may not be suitable for applications requiring frequent start-stop cycles at high duty factors, as soft starters generate heat during operation. It is also not intended for speed control or applications where high starting torque is required throughout the entire acceleration phase, such as heavy-duty crushers or mills.
Key specifications
Operational voltage: 400VAC
Rated current: 81A
Power capacity: 45kW
Control voltage: 110/230VAC
Phase: 3-phase
Installation should be performed by qualified personnel in accordance with local electrical regulations. The soft starter must be mounted in a clean, dry environment with adequate ventilation to ensure proper heat dissipation. Connect the power input and motor output terminals securely, ensuring that the control voltage is correctly wired to the designated terminals. Once installed, configure the starting parameters to match the specific requirements of the connected motor load.
What to consider before purchase
Ensure the motor power rating matches the 45kW capacity
Verify that the 110/230VAC control voltage is available in your control cabinet
Check the physical dimensions for mounting space requirements
Confirm the application does not exceed the thermal limits of the soft starter
For optimal performance, ensure that the soft starter is protected by appropriate motor circuit breakers or fuses and that the ambient temperature remains within the manufacturer's specified operating range.
