Siemens 3RV2917-4A 3-Phase Busbar for 2 Circuit Breakers Size S00 and S0

The Siemens 3RV2917-4A is a professional-grade 3-phase busbar system engineered for the efficient parallel connection of two circuit breakers. Designed specifically for sizes S00 and S0, this modular component streamlines electrical installations within industrial control cabinets and power distribution systems. By providing a standardized method for linking protection devices, it significantly reduces wiring complexity and enhances the overall organization of electrical panels.

Advantages

This busbar system offers a robust solution for power distribution, ensuring consistent electrical contact and reliable performance in demanding industrial environments. Its modular design allows for quick and secure installation, which saves valuable time during panel assembly. The inclusion of an end cover ensures that the system meets safety standards by protecting exposed connections, while the compact footprint helps optimize space within crowded control cabinets, making it an ideal choice for modern motor starter combinations.

Suitable for

• Parallel connection of two circuit breakers
• Industrial control cabinet assembly
• Motor starter combinations
• Electrical distribution systems requiring space-saving solutions

When it may not be suitable

This busbar is specifically designed for Siemens circuit breakers of sizes S00 and S0. It is not compatible with circuit breakers of different sizes or those from other manufacturers. Additionally, it is not intended for applications requiring more than two breakers in a single parallel line without further expansion modules.

Key specifications

• Phase configuration: 3-phase
• Compatible sizes: S00 and S0
• Capacity: 2 circuit breakers
• Included components: End cover

How to use

To install the busbar, align the terminals with the corresponding connection points on the two circuit breakers. Ensure that the breakers are mounted on a standard DIN rail to maintain proper spacing. Once aligned, press the busbar firmly into the terminals to establish a secure electrical connection. Finally, attach the provided end cover to the open end of the busbar to prevent accidental contact and ensure compliance with safety regulations.

What to consider before purchase

• Verify that your circuit breakers are of the S00 or S0 size category.
• Ensure the busbar length matches the physical layout of your control cabinet.
• Confirm that the electrical load requirements are within the rated capacity of the busbar.

Usage recommendations

Always ensure that the power supply is completely disconnected before installing or modifying any electrical components. Regularly inspect the connections for signs of wear or thermal stress to maintain long-term operational safety.
