The Schneider Electric LA9D40973 is a specialized star-delta mounting plate engineered for seamless integration with TeSys D contactors, specifically models D40 and D50. This accessory is a fundamental component in the construction of star-delta motor starters, a critical configuration for managing the high inrush currents associated with direct-on-line motor starts. By facilitating this starter type, the LA9D40973 contributes to reduced mechanical stress on motor components and improved power system stability.

Technical details

• Series: TeSys D
• Mounting Type: Star-Delta Starter Configuration
• Compatible Contactor Models: Schneider Electric D40, D50
• Functionality: Facilitates the electrical connection and physical mounting of contactors for star-delta starting sequences.
• Material: Durable construction suitable for industrial environments.
• Design: Engineered for precise alignment and secure mounting of specified TeSys D contactors.
• Purpose: Enables the reduction of motor starting current by connecting the motor windings in a star configuration initially, then switching to a delta configuration once the motor reaches operating speed.

Applications & compatibility

This mounting plate is essential for applications requiring controlled motor acceleration and reduced electrical system impact. It is commonly found in systems such as conveyor belts, pumps, fans, and compressors where smooth, efficient motor startup is paramount. The LA9D40973 ensures proper assembly of star-delta starters for these types of industrial machinery.
