Siemens 3RA2933-1DB1 Wiring Kit, Mechanical Kit for Load Feeders, 60 mm Busbar System Original Brand New

Overview

The Siemens 3RA2933-1DB1 SIRIUS Wiring Kit is a complete electrical and mechanical solution designed for assembling fuseless reversing load feeders in the SIRIUS modular system. This essential accessory simplifies the connection of components, specifically integrating a Size S2 motor starter protector (e.g., 3RV2) and contactor (e.g., 3RT2) combination onto a 60 mm busbar system utilizing side modules. It ensures a quick, error-free, and professional installation for reversing applications up to Size S2.

Key Technical Specification

Benefit

• Time-Saving Installation: Pre-assembled electrical and mechanical components drastically reduce wiring time and complexity compared to individual component wiring.
• Error Reduction: The dedicated kit eliminates potential wiring errors, leading to faster commissioning and greater operational reliability.
• System Integration: Provides seamless and robust integration of the load feeder combination onto the industry-standard 60 mm busbar system.
• Safety and Compliance: Ensures that the load feeder is correctly connected according to Siemens specifications, contributing to safe and compliant switchgear design.
• High Reliability: Part of the proven Siemens SIRIUS modular system, guaranteeing compatibility and durability.

Function

The 3RA2933-1DB1 functions as the critical link to create a complete, integrated load feeder for a reversing application. It mechanically joins the circuit breaker (motor starter protector) and the reversing contactor assembly, while simultaneously providing the electrical path to connect this unit to the main power distribution rail (the 60 mm busbar) via the included side modules. This one kit covers all necessary power and control connections between the core components and the busbar.
