Siemens 3RA1972-2E: Base Plate for Star-Delta Contactor Combinations Original Brand New

Overview

The Siemens 3RA1972-2E is a robust and essential base plate engineered for the secure and efficient mounting of a specific star-delta (wye-delta) starter combination. This product is designed to accommodate three specific SIRIUS contactors: two 3RT1.7 and one 3RT1.6. By providing a standardized mounting solution, the base plate ensures proper alignment and simplifies the installation of these components, which are crucial for the starting of electric motors.

Function

This base plate’s primary function is to serve as a stable foundation for assembling a star-delta starter. It precisely positions the two 3RT1.7 main and delta contactors and the single 3RT1.6 star contactor, ensuring the correct spatial relationship between them. This not only facilitates a clean and organized setup but also helps maintain the required electrical clearances and mechanical integrity of the motor control circuit. It is a critical component for building reliable and compact motor starters.

Benefit

• Simplified Installation: The pre-drilled holes and specific design make mounting the three contactors quick and straightforward, reducing assembly time and labor costs.
• Enhanced Reliability: Ensures proper alignment and secure mounting, which helps prevent mechanical stress and potential component failure.
• Improved Safety: A secure and organized mounting arrangement reduces the risk of electrical faults and improves overall system safety.
• Space Efficiency: Creates a compact and organized star-delta starter assembly, ideal for panel builders and system integrators with limited space.
