Siemens 3RA1953-2A SIRIUS Link Rail Set for 3RT1.5 Reversing Contactors, Size S6 Original Brand New

Product Overview

The Siemens 3RA1953-2A SIRIUS Link Rail Set is an essential accessory for building and wiring 3RT1.5 reversing contactor assemblies quickly and reliably. Part of the trusted SIRIUS modular system, this kit is specifically engineered for Size S6 contactors, offering a professional, pre-configured solution for industrial motor control applications. It replaces cumbersome individual wiring, significantly reducing installation time and eliminating wiring errors.

Key Benefit

• Fast & Easy Assembly: Dramatically reduces the time and effort required to wire two separate contactors for a reversing function.
• High Reliability: Pre-designed link rails ensure correct, secure connections every time, minimizing the risk of faults in your reversing contactor assembly.
• Space Optimization: The compact, modular design integrates neatly with 3RT1.5 contactors, helping to save valuable space in control cabinets.
• Integrated Phase Swapping: Includes built-in phase swapping on the output side, which is critical for motor reversal functionality.
• SIRIUS Quality: Manufactured by Siemens under the SIRIUS brand, guaranteeing industrial-grade quality, durability, and compatibility.

Function & Technical Detail

The 3RA1953-2A link rail set connects two Siemens 3RT1.5 power contactors (Size S6) to form a complete mechanical and electrical reversing starter unit.

• Application: Specifically for reversing contactor assemblies, and suitable for a Y-D (Star-Delta) starter configuration in Size S6.
• Connections: Provides the necessary connections for both the infeed side (power input) and the output side (motor connection).
• Core Function: Facilitates phase swapping on the output side to correctly reverse the direction of a three-phase motor.
• Product Type: Contactor Accessory / Wiring Module.
• Contactor Size Compatibility: Size S6 (e.g., Siemens 3RT105 series).
