Eaton 134938 DS7-342SX100N0-N DS7 Soft Starter 55 kW 100 A 230V

The Eaton DS7-342SX100N0-N is a Generation 7 three-phase soft starter rated at 100 A with a mains voltage range of 200 - 480 V AC and a control voltage of 110 - 230 V AC. Designed for soft starting of three-phase asynchronous motors, it incorporates internal bypass contacts to minimise semiconductor losses during normal running and supports inline motor powers up to 55 kW at 400 V. Frame size FS3 keeps the unit compact for panel builder installations.

Features and benefits:

• Internal bypass contacts engage after the motor reaches full speed, switching from semiconductor to mechanical conduction path and keeping running heat dissipation low
• Soft start function limits inrush current and mechanical shock at start-up, extending motor and driven equipment service life
• Two relay outputs (TOR and Ready) enable direct integration with PLCs and control panel supervisory circuits
• Wide mains voltage range of 200 - 480 V AC with 110 - 230 V AC control voltage supports global installation without hardware changes
• IP20 / NEMA 1 finger and back-of-hand protection for safe open-panel mounting in switchgear assemblies
• Suppression of closing transients and potential isolation between power and control circuits enhance operational reliability

Applications:

• Soft starting of three-phase asynchronous motors in industrial machinery and production lines
• Pump and fan motor control in HVAC and water treatment installations
• Compressor and conveyor motor starting where reduced mechanical and electrical stress at start-up is required
• Panel builder switchgear assemblies requiring compact Frame size FS3 motor control
• High-altitude process and utility plant environments up to 2000 m

Compliant with IEC/EN 60947-4-2, UL 508, and CSA-C22.2 No 14-05. Part of the Eaton DS7 Generation 7 soft starter series.
