## Long description

The Eaton DS7-340SX135N0-N is a high-performance 3-phase soft starter engineered to provide smooth and controlled motor acceleration and deceleration. Designed for industrial environments, this device operates at 400VAC and supports motors with a power capacity of up to 75kW and a rated current of 135A. By utilizing a 24V AC/DC control voltage, it effectively minimizes mechanical wear and electrical stress on the motor and connected drive components, ensuring a longer operational lifespan for your machinery.
Advantages
This soft starter offers significant benefits by reducing the high inrush currents typically associated with direct-on-line motor starting. By providing a gradual increase in voltage, it prevents mechanical shocks to belts, gears, and couplings, which helps maintain system integrity. Its compact design allows for efficient space utilization within control cabinets, while the integrated bypass technology ensures minimal heat dissipation during operation, contributing to overall energy efficiency and system reliability.
Suitable for
Industrial conveyor systems
Pumps and hydraulic systems
Fans and ventilation units
Compressors
Centrifugal machinery
When it may not be suitable
This device is not intended for applications requiring high-torque starting or frequent reversing of the motor direction. It is also not suitable for use in environments where the ambient temperature or humidity levels exceed the manufacturer's specified operating limits.
Key specifications
Operating voltage: 400VAC
Rated operational current: 135A
Motor power rating: 75kW
Control voltage: 24V AC/DC
Phase count: 3-phase
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. The soft starter is mounted within a suitable enclosure to protect against dust and moisture. Connect the 3-phase power supply to the input terminals and the motor leads to the output terminals. Ensure the 24V AC/DC control signal is correctly wired to the control inputs. Once installed, configure the acceleration and deceleration parameters via the device interface to match the specific requirements of the motor load.
What to consider before purchase
Verify that the motor's rated current does not exceed 135A.
Ensure the control system provides a stable 24V AC/DC supply.
Check that the available cabinet space allows for proper ventilation.
Confirm the application does not require frequent motor reversals.
Usage recommendations
Regularly inspect the electrical connections for tightness and ensure the cooling vents remain free of debris to maintain optimal thermal performance.
