Siemens 3RA2923-1DB2 SIRIUS Wiring Kit S0, Spring-Type, Fuseless Load Feeder, 60mm Busbar System Original Brand New

Overview

The Siemens 3RA2923-1DB2 Wiring Kit is a crucial accessory in the SIRIUS modular system, specifically designed for creating compact, reliable, and standardized fuseless load feeders (motor starter combinations) on a 60 mm busbar system. This complete electrical and mechanical connection kit utilizes spring-type terminals for fast, vibration-proof, and maintenance-free wiring, making installation efficient and secure. It is engineered for use with devices of Size S0 (such as 3RV2 motor starter protectors and 3RT2 contactors).

Key Features

This comprehensive kit includes all necessary parts for assembly:

• Wiring Module (Link Module): Provides the electrical connection between the circuit breaker (e.g., 3RV2) and the contactor (e.g., 3RT2).
• Busbar Adapter: Allows for direct and safe mounting and power connection to the 60 mm busbar system.
• Device Holder: Ensures stable mechanical mounting of the load feeder components.
• Side Modules: Complete the mechanical assembly and protection.
• Termination Type: Spring-Type Terminals (also known as push-in terminals), which are ideal for quick, tool-free connection of finely stranded or solid conductors.

Benefit

• Simplified Installation: Reduces wiring complexity and time by providing a pre-engineered, single-part solution for connecting components.
• High Reliability: The spring-type connection technology ensures a permanent, gas-tight, and vibration-resistant electrical contact, minimizing downtime.
• Space-Saving Design: Optimized for mounting on a 60 mm busbar system, facilitating a compact and organized control cabinet layout.
• System Compatibility: Seamlessly integrates Siemens SIRIUS Size S0 components (motor starter protectors and contactors) for building fuseless load feeders.
• Standardized Solution: Provides a consistent, repeatable method for building motor starters, simplifying documentation and maintenance.

Function

The 3RA2923-1DB2 wiring kit serves as the vital link for assembling a three-phase, fuseless load feeder. It electrically connects the motor protection circuit breaker (e.g., thermal magnetic breaker) to the contactor, and mechanically secures this entire assembly to the standard 60 mm busbar system for power supply, all while using quick-connect, spring-type technology.
