Eaton DS7-340SX016N0-N Soft Starter, 16 A, 200-480 V AC, 3-phase, 7.5 kW at 400 V 134912

Soft starter from the Eaton DS7 series for smooth starting and stopping of three-phase motors. The DS7-340SX016N0-N reduces mechanical stress and current peaks during motor start-up, extending the service life of driven components. With a rated operational current of 16 A and a voltage range of 200–480 V AC, it covers motor powers up to 7.5 kW at 400 V. The integrated bypass reduces power loss during continuous operation, while the built-in motor overload protection safeguards the motor. Control voltage is 110–230 V AC/DC, and the device supports optional SmartWire-DT communication modules. Mounting is possible on DIN rail or by screw fixing.

Advantages

Soft start and soft stop reduce mechanical wear and current peaks. Integrated bypass lowers heat generation and energy consumption. Motor overload protection is built in, eliminating the need for an external relay. The wide control voltage range allows flexible use in various control systems. Optional SmartWire-DT connectivity enables integration into automation networks.

Suitable for

• Conveyor belts and material handling systems
• Pumps and fans where smooth starting is required
• Compressors and small machinery with three-phase motors up to 7.5 kW
• Applications needing reduced starting current to avoid voltage dips
