Eaton 134927 DS7-342SX007N0-N DS7 Soft Starter 3 kW 7 A 230V

The DS7-342SX007N0-N is a Generation 7 Eaton DS7 soft starter for three-phase asynchronous motors, rated 7 A across a mains voltage range of 200 - 480 V AC. With 110/230 V AC control voltage and integrated internal bypass contacts, it delivers smooth motor acceleration while minimising heat dissipation during full-speed operation.

Features and benefits:

• Internal bypass contacts minimise steady-state heat dissipation once motor reaches full speed
• Potential isolation between power and control sections enhances panel safety
• Suppression of closing transients and DC components protects motor windings from stress
• Minimum ramp time of 1 s enables use as a fast-switching semiconductor contactor
• Climatic proofing to IEC 60068-2-3 and IEC 60068-2-30 suits humid industrial environments

Applications:

• Soft starting of three-phase asynchronous motors in industrial machinery and production lines
• Pump and fan drives requiring controlled inrush current reduction
• Conveyor and compressor systems where smooth acceleration ramps reduce mechanical wear
• HVAC and building services motor control panels with space constraints

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