Eaton 134934 DS7-342Sx041N0-N Soft Starter 3-Phase 41A 22kW 230V

The Eaton DS7-342SX041N0-N is a Generation 7 three-phase soft starter rated at 41 A for mains voltages of 200 - 480 V AC with a control voltage of 110/230 V AC. Designed for the controlled acceleration and deceleration of three-phase asynchronous motors, it incorporates an internal bypass relay that eliminates thyristor losses during steady-state run mode. Frame size FS3 keeps the footprint compact for panel integration.

Features and benefits:

• Internal bypass contacts eliminate thyristor losses in run mode, reducing heat dissipation to 7 W static
• Soft start ramp time from 1 s supports fast semiconductor contactor switching
• Suppression of closing transients and DC components protects motor windings from stress
• Two relay outputs (TOR, Ready) at 250 V AC simplify PLC and control panel integration
• Wide mains voltage range 200 - 480 V AC covers 50 Hz and 60 Hz networks worldwide
• Climatic proofing to IEC 60068-2-3 and IEC 60068-2-30 for operation in damp industrial environments

Applications:

• Conveyor and material handling drives requiring smooth, controlled motor acceleration
• Pump stations where soft start reduces water hammer and pipe stress
• Fan and HVAC systems needing reduced mechanical stress on belts and couplings
• Compressor applications demanding a controlled ramp to operating speed
• Industrial machinery with frequent start cycles requiring thermal management

Compliant with IEC/EN 60947-4-2. Part of the Eaton DS7 Generation 7 soft starter series.
