Eaton Soft Starter, 2 hp Power Rating, 4A Current Rating - 171740 DS7-340SX004N0-L


This soft starter delivers efficient motor control for industrial applications, designed for 3-phase loads operating between 200 and 480 V AC. With a Compact structure measuring 94mm in length, 45mm in width, and 130mm in height, it weighs only 0.41kg. It operates within an ambient temperature range of -40°C to +40°C, making it suitable for various environments while maintaining a degree of protection rated IP20.

Features & Benefits


• Soft start function reduces inrush current during motor start-up
• Internal bypass contacts enhance energy efficiency and reliability
• Voltage rating supports up to 480 V AC for diverse applications
• Single direction control ensures straightforward motor operation
• Compliant with CSA and UL standards for increased safety
• Can handle a rated operational current of up to 4 A

Applications


• Used for soft starting of three-phase asynchronous motors
• Ideal for industrial automation processes requiring smooth motor control
• Utilised in production lines with high load variability
• Suitable for HVAC systems that demand controlled motor performance

What is the impact of the internal bypass on performance?


The internal bypass reduces energy losses during normal operation, allowing for efficient motor control by minimising heat dissipation and enhancing overall reliability.

How does the soft start function benefit motor longevity?


The soft start function gradually increases motor voltage, decreasing mechanical stress and thermal impact, which extends the lifespan of both the motor and associated equipment.

What type of external reversing starter solution is required?


An external reversing starter is necessary to allow the soft starter to handle both forward and reverse motor operations, as this model is designed for single direction control only.
