Siemens 3RA2921-2F Hybrid Link Module for 3RV2.2 and 3RT2.2 Contactors, Multi-Unit Pack Original Brand New

Overview

The Siemens 3RA2921-2F is a hybrid link module designed for connecting Siemens SIRIUS 3RV2.2 motor starters with 3RT2.2 contactors. This multi-unit pack provides both the electrical and mechanical linking components needed to create a compact and efficient starter combination.

It’s a crucial accessory for building integrated control systems, simplifying wiring and reducing assembly time. The module is specifically engineered for screw-type technology on the 3RV2.2 and spring-type technology on the 3RT2.2, ensuring a secure and reliable connection.

Benefit

• Saves Time and Effort: The hybrid link module streamlines the assembly of motor starters and contactors, eliminating the need for complex and time-consuming individual wiring.
• Reduces Wiring Errors: Pre-fabricated links ensure correct electrical connections, minimizing the risk of wiring mistakes and improving system reliability.
• Compact Design: Integrates components closely, saving valuable panel space and allowing for a more compact overall design.
• Enhanced Reliability: Provides a robust mechanical and electrical connection that resists vibration and ensures consistent performance in industrial environments.
• Cost-Effective: The multi-unit packaging offers a practical and economical solution for larger projects or stock-keeping.

Function

The 3RA2921-2F module serves as a bridge, providing both a mechanical and an electrical connection between a 3RV2.2 circuit breaker or motor starter and a 3RT2.2 contactor. The mechanical function securely locks the two devices together, ensuring they are properly aligned and stable. The electrical function provides the necessary power connections between the two components, simplifying the power circuit and reducing the number of individual wires and terminals required.
