Siemens 3RA1943-3D Wiring Module Top, 10 mm Contactor Assembly Spacer Original Brand New

Overview

The Siemens 3RA1943-3D is a high-quality, specialized wiring module designed for creating compact and reliable contactor assemblies within industrial control panels. This module serves as the top connection component, specifically engineered for applications where contactors are mounted with a 10 mm spacing (center-to-center distance). Part of the trusted Siemens SIRIUS industrial controls portfolio, the 3RA1943-3D streamlines the wiring process, reduces installation time, and ensures a professional, vibration-resistant connection.

Key Features & Function

• Optimized for Spacing: Precisely engineered for contactor assemblies utilizing a 10 mm spacing between devices, facilitating high-density panel design.
• Top Connection: Designed for connecting the control/power circuit wiring on the top side of the contactor assembly.
• Reduced Wiring Time: Eliminates the need for individual jumpers and manual wiring of common circuits, significantly decreasing assembly and commissioning time.
• High Reliability: Ensures a secure, standardized, and maintenance-free electrical connection, minimizing potential fault points compared to traditional wiring methods.
• Compatibility: Designed for use with specific Siemens SIRIUS contactor and starter combinations (check technical specifications for exact compatibility with contactor sizes).

Benefit

1. Saves Panel Space: The 10 mm design allows for maximum component density, crucial in space-constrained enclosures.
2. Professional Installation: Provides a clean, standardized, and highly repeatable wiring solution, improving the professional appearance and quality of the finished panel.
3. Cost Efficiency: Reduces labor costs associated with manual wiring and simplifies troubleshooting.
4. Enhanced Safety: Standardized connections decrease the risk of wiring errors and short circuits.
