Model and Specifications of Small Busbars for Computer Rooms

Small busbar systems for computer rooms are typically compact, modular, and rated for currents up to 400–630 A, with 40 mm and 60 mm bar center distances being common.

Key Models and Types

Siemens 8US Busbar System: Designed for mounting current-limiting devices such as fuse switch disconnectors and circuit breakers directly onto the busbars. It supports horizontal mounting and is suitable for low to medium power ranges, typically up to 400 A. The system is modular, allowing flexible installation in control cabinets and computer room distribution boards, with short-circuit strength dependent on busbar cross-section and support spacing.

Siemens 60 mm Compact Busbar System: Space-saving solution for medium to high performance ranges (up to 630 A, with special profiles up to 1600 A). Ideal for Motor Control Centers and power distribution in computer rooms where compact installation is required.

Rittal Ri

Line Busbar Systems: Available in 40 mm and 60 mm bar center distances, with 3-pole or 4-pole configurations. Features include tool-free mounting, short-circuit resistance up to 65 kA, and full contact hazard protection. The 40 mm system is particularly space-efficient, suitable for front plug-and-lock connections, while the 60 mm system allows simple, tool-free component connections.

Specifications and Features

Current Ratings: 40 mm busbars typically handle up to 400 A, while 60 mm systems can handle 630 A or higher depending on the profile. Material: Copper or aluminum bars for low-loss energy transport. Modularity: Systems allow easy expansion and integration of new devices without major rewiring.

Safety: Full contact hazard protection, short-circuit resistance, and secure mounting to prevent vibration. Installation: Horizontal mounting is common; supports and adapters ensure proper short-circuit strength. Tool-free connections simplify assembly and maintenance.

Digital Integration: Siemens SIVACON 8PS busbars can be planned using SIMARIS software, providing digital twins, energy data integration, and IoT connectivity for monitoring and management.

Applications in Computer Rooms

Power distribution to server racks and network equipment. Integration with protective devices for overload and short-circuit protection. Space-efficient installation in control cabinets or dedicated busbar enclosures.

Modular expansion for future upgrades or additional loads. These small busbar systems provide a reliable, compact, and flexible solution for computer room power distribution, ensuring safety, efficiency, and ease of maintenance.
