## Summary description

The Eaton SDAINLM115 is a pre-wired star-delta starter designed for reliable motor control in industrial applications. Rated for 55kW at 400V and 115A in AC-3 duty, this starter ensures smooth motor acceleration and reduced starting current. It is an essential component for managing three-phase induction motors, providing efficient operation and protection in demanding electrical systems.

## Long description

The Eaton SDAINLM115 Star-Delta Starter is a robust, pre-wired solution engineered for the efficient control and protection of three-phase induction motors in industrial environments. Designed to handle a power rating of 55kW at 400V, this starter facilitates a controlled transition from star to delta connection, which significantly minimizes the high inrush currents typically associated with motor startup. By managing the electrical load during the acceleration phase, it helps maintain system stability and extends the operational lifespan of the motor and connected mechanical components.
Advantages
This star-delta starter offers a streamlined installation process due to its pre-wired configuration, which reduces wiring errors and saves valuable time during panel assembly. The unit is built to high industrial standards, ensuring reliable performance under demanding AC-3 duty cycles. Its compact design allows for efficient use of space within control cabinets, while the integrated components work in harmony to provide consistent motor protection and smooth operational transitions, ultimately contributing to lower mechanical stress and improved energy efficiency in industrial drive systems.
Suitable for
Industrial ventilation and fan systems
Large centrifugal pumps
Conveyor belt drives
Compressor motor control
Heavy-duty industrial machinery
When it may not be suitable
This starter is specifically designed for three-phase induction motors and is not suitable for single-phase applications or motors that do not support star-delta starting configurations. It should not be used in environments exceeding its rated current or voltage specifications, as this could lead to equipment failure or safety hazards.
Key specifications
Power rating: 55kW at 400V
Rated operational current: 115A (AC-3)
Configuration: Pre-wired star-delta starter
Application: Three-phase induction motors
How to use
The Eaton SDAINLM115 should be installed by a qualified electrician within a suitable electrical enclosure. Ensure that the motor terminals are correctly wired for star-delta operation according to the manufacturer's wiring diagram. The device must be connected to a power supply that matches the rated voltage and frequency. Once installed, the timing relay should be adjusted to ensure the transition from star to delta occurs at the appropriate speed for the specific motor load.
What to consider before purchase
Verify that the motor nameplate data matches the 55kW and 115A ratings.
Ensure the control cabinet has sufficient space for the physical dimensions of the starter.
Confirm that the supply voltage is compatible with the coil voltage requirements.
Check that the motor is configured for six-lead star-delta starting.
Usage recommendations
Regularly inspect the electrical connections for tightness and check the contactors for signs of wear to ensure long-term reliability. Always follow local electrical codes and safety regulations during installation and maintenance.
