Siemens 3RA2911-2FA00 Hybrid Link Module Electrical & Mechanical Link for SIRIUS 3RV2.1, 3RT2.1 Spring-Type Original Brand New

Overview

The Siemens 3RA2911-2FA00 Hybrid Link Module is an essential accessory from the SIRIUS modular system, designed to create seamless electrical and mechanical connections between components in motor starter combinations. This hybrid module is specifically engineered to link a SIRIUS 3RV2.1 Motor Starter Protector/Circuit Breaker featuring screw-type technology with a SIRIUS 3RT2.1 Contactor utilizing spring-type technology.

This coupling module simplifies wiring, reduces installation time, and ensures a robust, reliable connection between the devices, typically in Size S00 applications. It is critical for building efficient and space-saving fuseless load feeders.

Benefit

• Time-Saving Installation: Rapidly connects the motor starter protector and contactor, significantly reducing wiring time and effort compared to traditional individual wiring.
• High Reliability: Provides a secure, vibration-resistant electrical and mechanical connection, minimizing connection faults.
• Space Optimization: Creates a compact load feeder assembly, saving valuable space within the control cabinet.
• Hybrid Compatibility: Unique design allows for coupling devices with different terminal technologies (screw-type and spring-type), offering installation flexibility.
• System Integration: Fully integrated with the Siemens SIRIUS modular system, ensuring seamless compatibility and performance.

Function

The 3RA2911-2FA00 acts as an integrated connector, performing two primary functions:

1. Mechanical Coupling: Securely fixes the 3RV2.1 Motor Starter Protector and the 3RT2.1 Contactor side-by-side, creating a single, integrated motor starter assembly (load feeder).
2. Electrical Connection: Establishes the necessary current paths between the output of the motor starter protector and the main circuit input of the contactor, eliminating the need for separate main circuit wiring between the two devices.
