Siemens 3RV2917-1A 3-Phase Busbar for 2 Circuit Breakers with Left-Side Infeed

The Siemens 3RV2917-1A is a professional-grade 3-phase busbar system engineered to streamline the electrical connection of two SIRIUS 3RV2 circuit breakers. Designed specifically for sizes S00 and S0, this component facilitates a clean and organized power distribution layout within industrial control cabinets. By utilizing a left-side infeed configuration, it reduces the need for complex individual wiring, thereby improving installation efficiency and system reliability.

Advantages

This busbar system offers significant benefits for electrical panel builders and maintenance technicians by minimizing installation time and reducing the risk of wiring errors. Its robust construction ensures a stable electrical connection, while the included end cover provides essential protection against accidental contact, enhancing overall safety in the cabinet. The modular design allows for a compact arrangement of circuit breakers, which is ideal for space-constrained environments where high-density component mounting is required.

Suitable for

• Industrial control cabinet power distribution
• Connecting two SIRIUS 3RV2 circuit breakers
• Applications requiring space-saving electrical layouts
• Systems utilizing S00 and S0 frame sizes

When it may not be suitable

This busbar is specifically designed for a left-side infeed configuration and may not be compatible with panel layouts requiring right-side or center-fed power distribution. It is also limited to connecting exactly two circuit breakers and cannot be used for applications requiring a different number of devices or different frame sizes outside of the S00 and S0 range.

Key specifications

• Phase configuration: 3-phase
• Compatibility: SIRIUS 3RV2 circuit breakers
• Supported sizes: S00 and S0
• Infeed position: Left-side
• Included accessories: End cover

How to use

To install the busbar, ensure that the power supply to the control cabinet is completely disconnected. Align the busbar with the terminals of the two SIRIUS 3RV2 circuit breakers, ensuring the left-side infeed is correctly positioned. Secure the busbar firmly to the terminals according to the torque specifications provided in the circuit breaker documentation. Once the connection is verified, attach the included end cover to the open end of the busbar to ensure proper insulation and safety compliance.

What to consider before purchase

• Verify the frame size of your circuit breakers (S00 or S0)
• Confirm that your cabinet layout supports a left-side infeed
• Ensure the total current load does not exceed the busbar rating
• Check available space in the control cabinet for the busbar assembly

Usage recommendations: Always perform a final inspection of all terminal connections after installation to ensure they are tightened to the manufacturer's specified torque values. Regularly check the busbar for signs of wear or thermal stress during routine maintenance intervals.
