Siemens 3RT1936-4BA31, 3-Pole Paralleling Link for 3RT2.3 Contactors Original Brand New

Overview

The Siemens 3RT1936-4BA31 is a specialized accessory designed for efficiently connecting two SIRIUS 3RT2.3 power contactors in parallel. This 3-pole paralleling link is engineered for terminal-less connection, ensuring a fast, secure, and highly reliable electrical connection without the need for additional wiring terminals. It’s a critical component for applications requiring redundant power supply or increased load capacity by utilizing two contactors simultaneously.

Key Features & Function

• Terminal-Less Design: Facilitates rapid, tool-free mounting and disassembly, significantly reducing installation time and complexity.
• 3-Pole Configuration: Provides simultaneous and secure electrical connection across all three main poles of the paired contactors.
• Dedicated Compatibility: Specifically designed for seamless and precise fitting with Siemens SIRIUS 3RT2.3 power contactors.
• Secure Paralleling: Ensures both contactors operate in synchronization for enhanced system reliability and optimized current sharing.
• High Quality & Reliability: Manufactured by Siemens, guaranteeing the quality and robustness expected for industrial control applications.
• Function: Electrically and mechanically links the main circuit terminals of two adjacent 3RT2.3 contactors to enable paralleling (e.g., for motor starting with redundant supply or increased current handling).

Benefit

• Saves Time: The terminal-less connection dramatically speeds up the assembly process compared to traditional wiring methods.
• Reduces Errors: Provides a fixed, engineered connection, minimizing the risk of wiring mistakes or loose terminal connections.
• Optimizes Panel Space: Its compact design allows for a clean and space-efficient layout within the control cabinet.
• Increased System Capacity/Redundancy: Allows the combined current handling capacity of two contactors to be utilized or provides an immediate path for system redundancy.

Application

• Motor starter panels where multiple contactors are paralleled for higher current or redundant operation.

• Industrial control cabinets using the Siemens SIRIUS 3RT2.3 range in switching or power distribution roles.

• Control system upgrades or retrofits where consistent Siemens accessory usage is required to maintain warranty / certification compliance.
