Aardingsrail EFB Elektronik K3930V42

The EFB Elektronik K3930V42 grounding bar is designed for installation inside 42U, 19" server and network racks to provide a reliable grounding point for equipment. Constructed to fit standard rack dimensions, this grounding bar measures 15 mm in width, 5 mm in depth and 1800 mm in height, offering continuous earthing along the rack height to reduce potential differences and improve electrical safety of mounted devices.

Advantages

This grounding bar provides a stable and low-impedance grounding path within a 19" rack. Its slim profile maximizes usable rack space while delivering full-height coverage for devices mounted across the rack. The robust mechanical construction ensures secure mounting and long-term reliability in data centers, server rooms and telecommunication cabinets.

Suitable for

• Grounding servers and networking equipment in 42U, 19" racks
• Telecommunications cabinets and data center rack installations
• Racks requiring a continuous, full-height earth connection for multiple devices

Key specifications

• Designed for 42U rack height
• Compatible with standard 19" rack width
• Dimensions: 15 mm width × 5 mm depth × 1800 mm height
• Full-height grounding bar for continuous earthing along the rack
• Suitable for vertical installation inside the rack frame

How to use

Mount the grounding bar vertically inside the 19" rack frame where it provides best access to equipment grounding points. Secure the bar to the rack structure using appropriate hardware and connect the bar to the facility earth using a suitably sized grounding conductor. Attach equipment grounding leads to the bar at appropriate points along its height to ensure all devices share the same reference to earth.

Recommendations

For safe and effective grounding, use conductor sizes and connectors that comply with local electrical codes and the rack equipment manufacturers' guidelines; verify continuity and low resistance after installation and periodically as part of routine maintenance.
