Benefit

1. Simplified Assembly: Reduces installation time by providing pre-engineered mounting positions for the three contactors required in a star-delta starter setup.
2. Increased Reliability: Ensures consistent and precise alignment of the contactors, which is crucial for the correct operation of interlocks and wiring.
3. Space Efficiency: Allows for a compact arrangement of contactors, optimizing panel space within the control cabinet.
4. SIRIUS System Compatibility: Seamlessly integrates with the wide range of Siemens SIRIUS industrial controls, ensuring high-quality performance and longevity.
5. Versatile Use: Accommodates common contactor size combinations ($3\times \text{S}2$ or $2\times \text{S}2+1\times \text{S}2$ equivalents within the specified 3RT2 series) for various motor power ratings.

Function

The primary function of the 3RA2932-2F base plate is to serve as a robust mechanical foundation for a star-delta contactor assembly. It secures the Main, Delta, and Star contactors (3RT2 series) in the correct relative positions and distance, facilitating the installation of pre-wired components or short-circuiting links required for the motor starter wiring.
