Features and benefits:

• Integrated internal bypass contacts reduce heat dissipation during full-speed run mode
• Suppression of closing transients and DC components protects motor windings during starting
• Minimum ramp time of 1 s enables fast switching in semiconductor contactor mode
• Two relay outputs (TOR and Ready) simplify integration with PLC and control systems
• Climatic proofing to IEC 60068-2-30 (cyclic damp heat) and IEC 60068-2-3 (constant damp heat) for demanding environments
• Finger and back-of-hand proof IP20 enclosure protects against direct contact

Applications:

• Pump and fan motor starting in HVAC and water treatment installations
• Conveyor and compressor motor control in industrial automation panels
• Controlled acceleration of three-phase motors to reduce mechanical stress on couplings and belts
• Panel assemblies requiring compact vertical DIN rail mounting of motor starters
• Industrial processes where reduced starting current limits network voltage disturbances

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