Siemens 3RA2921-2GA00 Link Module for 3RV2021/3RW3/3RW4, Spring-Type Terminal Original Brand New

Overview

The Siemens 3RA2921-2GA00 Link Module is an essential accessory designed for the seamless and robust electrical and mechanical connection of Siemens switching and control gear. Specifically engineered for use with the 3RV2021 Circuit Breaker and the 3RW3/3RW4 Soft Starters (models 3RW3.2 and 3RW402), this module ensures a secure and integrated unit. By eliminating the need for complex, manual wiring between devices, it significantly reduces installation time and minimizes the potential for wiring errors. This link module is equipped with advanced Spring-type Terminals for vibration-proof and maintenance-free connections.

Key Features & Benefit

• Fast, Error-Free Assembly: Provides a single, fixed solution for connecting compatible devices, simplifying the setup process and ensuring perfect alignment every time.

• Secure Spring-Type Connection: Utilizes reliable spring-type terminals, which offer excellent resistance to vibration and do not require re-tightening, leading to reduced maintenance costs and enhanced operational safety.

• Integrated Solution: Offers both electrical and mechanical coupling in one unit, creating a compact and professional connection assembly.

• Compatibility: Designed specifically for the Siemens SIRIUS series, ensuring perfect fit and optimal performance with the 3RV2021, 3RW3.2, and 3RW402 components.

• Space Saving: Creates a highly compact, contiguous unit, freeing up valuable space within the control cabinet.

Functionality & Use Cases

• Direct-on-Line (DOL) Starters: Ideal for DOL motor-starter protector to contactor assemblies without needing a separate contactor base.

• Control Panels: Simplifies wiring across control cabinet components, especially in industrial automation, motor control, HVAC systems, and pump control.

• Retrofit & Maintenance: Use this link module when upgrading or replacing existing 3RV2021 or 3RW3-series components to improve system reliability.
