Benefit

1. Significant Time Savings: Spring-type technology and pre-assembled components reduce wiring and installation time compared to conventional screw terminals.
2. Error Prevention: The use of pre-tested wiring modules minimizes the risk of wiring mistakes, leading to higher reliability and faster switchgear acceptance.
3. Maximum Reliability: Spring-loaded connections offer a secure, gas-tight, and vibration-proof connection, ensuring operational safety and long-term stability.
4. System Compatibility: Fully integrated into the Siemens SIRIUS modular system, guaranteeing perfect technical and dimensional coordination with other components (e.g., 3RV2 and 3RT2 devices in Size S0).
5. Easy Installation: Designed for simple, clip-on mounting onto a standard rail, simplifying panel construction.

Function

The 3RA2923-1BB2 Wiring Kit serves as the crucial link that connects a motor starter protector (e.g., Siemens 3RV2) and a contactor (e.g., Siemens 3RT2) into a complete, fuseless load feeder unit. It provides the power circuit connection and ensures mechanical stability, streamlining the assembly process for various motor control applications.
