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

Overview

The Siemens 3RA1972-2F is a robust and essential base plate designed for the secure and streamlined mounting of a star-delta (wye-delta) motor starter combination. Specifically engineered to accommodate three Siemens 3RT1.7 contactors, this base plate provides a stable foundation, simplifying the assembly process and ensuring a professional, compact, and reliable motor control solution. Its precise design eliminates the need for complex custom mounting, saving time and labor costs.

Benefit

• Streamlined Installation: The pre-designed layout for three contactors makes assembly quick and straightforward, reducing installation time.
• Enhanced Reliability: A single, solid base plate provides a secure mounting point, preventing misalignment and ensuring the long-term stability of the contactor combination.
• Space-Saving Design: Integrates the contactors into a compact unit, optimizing panel space and leading to a more efficient and organized control cabinet.
• Durable and High-Quality: Manufactured by Siemens, a leader in industrial automation, ensuring the product’s quality, durability, and compatibility with other Siemens components.
• Cost-Effective Solution: By simplifying assembly and reducing the risk of installation errors, this base plate offers a cost-effective way to build a star-delta starter.

Function

The primary function of the Siemens 3RA1972-2F base plate is to provide a dedicated, non-conductive surface for the fixed and precise mounting of a three-contactor combination used in star-delta motor starting applications. It ensures the correct spacing and alignment of the contactors (specifically 3x 3RT1.7), which is crucial for the proper electrical and mechanical operation of the starter. This simplifies wiring and integration into a larger motor control circuit.
