Description
The DS7-340SX100N0-L soft starter from Eaton is designed for 3-phase AC motors, offering a rated current of 100 A and supporting supply voltages from 200 to 480 V AC. With a control voltage of 24 V AC/DC, it provides reliable soft-start functionality while protecting motors and minimizing mechanical stress. Its FS3 frame size ensures easy integration into industrial panels while maintaining a compact footprint.

Equipped with 2 relay outputs (TOR, Ready), the DS7 soft starter allows flexible monitoring and control of motor startup sequences. The ramp time can be adjusted from 0 to 30 seconds, ensuring smooth acceleration and reducing the risk of electrical or mechanical shock during startup. The device operates reliably across an ambient temperature range of -40 °C to +40 °C and is rated IP20 for protection against solid objects.

The DS7 series employs an asymmetrical trigger phase control method, a patented Eaton technology, to suppress DC components typically seen in 2-phase soft starters. This prevents the formation of an elliptical rotating field, which can cause uneven motor starts and increased acceleration time, making the DS7 comparable in performance to 3-phase soft starters.

Designed for industrial environments, the DS7-340SX100N0-L features mechanical shock resistance up to 8 g/11 ms, vibration resistance 2M2 (EN 60721-3-2), and altitude derating for installations above 1000 m. Its flexible design allows for reliable motor starting across a wide range of applications from 1.1 kW to 110 kW at 400 V supply voltage.
