Siemens 3RA2933-2BB1 Wiring Kit, Screw Terminal for Star-Delta S2/S2/S2 Original Brand New

Overview

The Siemens 3RA2933-2BB1 is an essential, pre-assembled wiring kit designed to provide a quick, reliable, and standardized electrical and mechanical connection for building a star-delta (wye-delta) combination using SIRIUS size S2 contactors. This high-quality accessory ensures fast commissioning and error-free wiring, significantly reducing installation time and complexity. It is specifically tailored for screw terminal connection type, making it a robust and dependable choice for demanding industrial applications requiring the smooth, reduced-current starting of three-phase motors.

Key Features & Function

• Simplified Star-Delta Assembly: Provides all necessary mechanical and electrical links to connect three SIRIUS S2 contactors (main, star, and delta) for a complete star-delta starter setup.

• Reduced Wiring Time: Replaces complex individual wiring, offering a plug-and-play-like installation that saves significant time during panel building.

• Mechanical and Electrical Integration: Includes both the insulated electrical conductors and the mechanical interlocks/spacers required for the star-delta configuration.

• Compatibility: Designed for use with SIRIUS 3RT2 Size S2 contactors, ensuring a perfect fit and reliable operation within the Siemens control gear system.

• Connection Type: Optimized for secure and reliable screw terminal connections.

• Safety and Standards: Conforms to international standards, ensuring safe and compliant operation in industrial environments.

Benefit

• Installation Efficiency: Dramatically cuts down the time spent on manual wiring and troubleshooting.

• Reliability: Factory-tested components guarantee a secure, standardized, and high-quality electrical connection, minimizing the risk of wiring errors.
