Siemens 3RA1943-3E Wiring Module Bottom for Contactor Assembly, 10 mm Distance Original Brand New

Overview

The Siemens 3RA1943-3E is a crucial bottom wiring module (link module) from the SIRIUS modular system, specifically engineered for the assembly of two contactors (typically for reversing starter combinations). This high-quality accessory is designed to simplify and accelerate the wiring process for Size S3 contactor combinations, maintaining the required 10 mm clearance between the contactors. By using this prefabricated module, panel builders and engineers can drastically reduce wiring time, minimize potential errors, and achieve a professional, space-efficient control cabinet layout.

Benefit

• Reduced Wiring Time: Eliminates complex individual wire connections between the bottom terminals of two contactors, saving significant installation time.
• Increased Reliability: Minimizes wiring errors, improving the overall reliability and safety of the contactor assembly.
• Space Optimization: Enables a compact reversing starter configuration by maintaining the optimal 10 mm spacing between the Size S3 contactors.
• Simple Installation: Features an easy-to-use plug-and-play design for quick, direct mounting onto the contactor terminals.
• SIRIUS System Integration: Guarantees seamless compatibility and performance within the Siemens SIRIUS industrial control and switching devices ecosystem.

Function

• Facilitates proper wiring alignment in contactor assemblies.

• Improves electrical safety and reliability.

• Supports efficient modular assembly in industrial automation systems.

Application

Ideal for use in:

• Building Reversing Contactor Assemblies (Reversing Starters)
• Motor Control Centers (MCCs)
• Industrial Control Panels and Cabinets
• Any application requiring compact, reliable interconnection of two Size S3 contactors.
