## Summary description

The Eaton SDAINLM90 is a pre-wired star-delta starter designed for reliable motor control in industrial applications. With a power rating of 45kW and a rated operational current of 90A at 400V AC-3, this unit ensures smooth motor starting and reduced inrush current. It is an essential component for managing three-phase induction motors, providing robust performance and operational safety in demanding electrical systems.

## Long description

The Eaton SDAINLM90 Star-Delta Starter is a pre-wired industrial control solution engineered for the efficient management of three-phase induction motors. Designed to handle a power rating of 45kW and a rated operational current of 90A at 400V AC-3, this starter provides a reliable method for controlling motor acceleration. By utilizing the star-delta starting method, the unit effectively reduces the high inrush current typically associated with direct-on-line starting, thereby minimizing mechanical stress on the motor and electrical strain on the power supply network.
Advantages
This star-delta starter offers significant benefits for industrial motor management by facilitating a controlled transition during the startup phase. The pre-wired configuration simplifies the installation process, reducing the time and labor required for setup. Its robust construction ensures consistent performance in demanding environments, while the integrated design promotes operational safety and longevity for connected motor systems. By limiting current peaks, it helps maintain the stability of the electrical infrastructure and extends the service life of the motor components.
Suitable for
Industrial motor control systems
Three-phase induction motor starting
Applications requiring reduced inrush current
Manufacturing and processing machinery
Ventilation and pump systems
When it may not be suitable
This starter is specifically designed for three-phase induction motors and is not suitable for single-phase motor applications. It may also be inappropriate for systems where the motor torque requirements during the star-connection phase are higher than what the motor can provide, as this could lead to failure to reach the necessary speed for transition.
Key specifications
Power rating: 45kW
Rated operational current: 90A
Operational voltage: 400V AC-3
Configuration: Pre-wired star-delta
Application: Three-phase induction motors
How to use
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The unit must be mounted in a suitable enclosure that provides adequate protection against environmental factors. Ensure that the motor terminals are correctly connected to the starter output according to the provided wiring diagram. Before energizing, verify that all connections are secure and that the thermal overload settings are adjusted to match the specific motor current rating. Once installed, the starter operates automatically to transition the motor from star to delta configuration based on the internal timing mechanism.
What to consider before purchase
Verify the power and current requirements of your specific motor
Ensure the supply voltage matches the 400V rating
Check available space for mounting the starter unit
Confirm compatibility with existing control circuit voltages
Usage recommendations
Regularly inspect the electrical connections for tightness and check the starter for any signs of overheating or mechanical wear to ensure continued safe and reliable operation.
