3RA2911-2A

Description

Overview

The Siemens SIRIUS 3RA2911-2A Link Module is an essential accessory designed for the efficient, tool-free assembly of SIRIUS motor starter combinations. It provides a reliable and integrated electrical and mechanical connection between the 3RV2011 Motor Starter Protector (Circuit Breaker) and the 3RT201 Contactor. This specific version features robust spring-type terminals (cage clamp technology) for quick, vibration-proof, and maintenance-free wiring. Supplied in a multi-unit packaging format, the 3RA2911-2A is ideal for high-volume panel builders and industrial applications requiring streamlined assembly processes.

Key Features & Benefit

• Rapid Assembly: Allows for fast, error-free mounting of motor feeders, significantly reducing installation time and labor costs compared to traditional wiring.
• Integrated Connection: Provides both the electrical power connection and the secure mechanical coupling between the circuit breaker and contactor.
• Spring-Type Technology: Utilizes secure spring-type terminals (cage clamp) to ensure a high-contact-pressure, gas-tight connection that is immune to vibration and temperature cycling. This virtually eliminates the need for routine tightening maintenance.
• Space-Saving Design: Its compact, direct-mounting nature saves critical space within the control cabinet.
• High Reliability: Engineered by Siemens SIRIUS for maximum durability and consistent performance in demanding industrial environments.

Function/Application

The primary function of the 3RA2911-2A module is to link the main terminals of the 3RV2011 (Size S00) circuit breaker to the main terminals of the 3RT201 (Size S00) contactor. This forms a complete, pre-wired motor starter configuration, ready for installation in machinery control panels, HVAC systems, pumping stations, and general industrial automation applications.
