Earthing bar SCHROFF M5 440 mm with 20 grounding points model 20118-860

SCHROFF earthing bar M5, 440 mm long with 20 grounding points, is designed to provide a reliable common earth connection inside electronic enclosures and server cabinets. The metal bar accepts M5 terminal connections and facilitates orderly, low-resistance grounding of chassis, racks and components. Its 440 mm length and evenly spaced points simplify cable routing and termination in industrial and IT installations where multiple ground connections are needed.

Advantages

The earthing bar offers a compact, robust solution for centralizing protective earth connections. Its standardized M5 points allow easy attachment of ring or fork terminals and ensure consistent mechanical and electrical contact. The metal construction provides durable conductivity and mechanical stability, while the multiple attachment points reduce the need for individual ground wiring to the cabinet frame. Designed for installation in equipment racks and electronic enclosures, the bar helps maintain tidy cabling and repeatable grounding practices.

Suitable for

• Grounding chassis and subassemblies inside server cabinets
• Central earth point for industrial control panels and switchgear
• Consolidating multiple protective earth connections in telecom racks
• Applications requiring multiple M5 grounded terminations in compact spaces

Key specifications

• Length: 440 mm
• Terminal type: M5 grounding points (20 positions)
• Number of grounding points: 20
• Material: conductive metal suitable for earthing (plated/treated for corrosion resistance)
• Mounting: designed for attachment inside enclosures and server cabinets

How to use

Mount the earthing bar on a suitable flat surface inside the enclosure or on the cabinet frame using compatible fasteners. Terminate individual ground conductors with appropriately sized ring or fork terminals for M5 screws and secure them to each grounding point, ensuring tight mechanical and electrical contact. Verify continuity between the bar and the equipment protective earth to confirm correct installation. Route cables to avoid mechanical stress and maintain separation from signal lines where required.

Usage recommendations

Use conductors and terminals rated for the expected fault current and follow local electrical standards for earthing. Apply anti-oxidation compound on connections if recommended for the installation environment. Periodically inspect attachment points for corrosion and tightness, and ensure the bar remains bonded to the main earthing system of the installation.
