Rittal DK Earth Rail, Horizontal, 450 mm — Copper Potential Equalisation Rail for IT Enclosures
450 mmE-Cu 15 x 5 mmapprox. 200 A20 x M5 points
The Rittal 7113000 is a horizontal copper earth rail, 450 mm long with a 15 x 5 mm cross-section, that gives an IT or industrial enclosure a central potential equalisation point with 20 M5 connection points for bonding doors, side panels, mounting frames and installed equipment.
In a rack full of switches, patch panels and power distribution, every metal part should sit at the same potential. Instead of running separate earth wires from each component to a single stud, you mount this rail horizontally inside the enclosure and land every bonding conductor on it. That keeps wiring short and tidy, makes inspection easier, and gives one clear point to connect to the building earth.
Before you order: Rittal lists this rail for AX, VX, VX IT, TS and TS IT enclosures (and the AX 3-part wall-mounted enclosure) with a width over 600 mm and a depth over 600 mm, i.e. 800 mm width or depth. It does not fit enclosures 600 mm wide or deep. Electrical bonding must be installed by a qualified electrician according to local regulations.
What's in the Box
- 1 x earth rail, E-Cu, 450 mm
- 20 connection points with M5 screws
- 2 earth connections for 25 mm² conductors
- 2 isolators
- Assembly parts
What It Means in Practice
- One common bonding bar for the whole enclosure instead of daisy-chained earth wires.
- Twenty M5 points is enough for doors, side panels, roof, 19-inch frame and a set of devices, with spare points left over.
- The two 25 mm² earth connections take the main conductor to the building earth.
- Supplied isolators allow insulated mounting where the rail must not touch the frame directly.
What Will Not Work
- Enclosures 600 mm wide or 600 mm deep — the rail needs a width or depth of 800 mm.
- Non-Rittal cabinets: Rittal only publishes compatibility with its own AX, VX, TS families.
- Earth conductors, cable lugs and bonding straps are not included — order them for the cross-sections your installation needs.
- It is not a replacement for the building protective earth; it is a collection point that must itself be connected by an electrician.

Frequently Asked Questions
Why do I need an earth rail in a network rack?
Bonding all metal parts to one point prevents voltage differences between components, which matters for safety and for reducing interference on copper data cabling.
Does it fit my 600 mm wide rack?
No. Rittal specifies enclosures wider and deeper than 600 mm (800 mm). For 600 mm enclosures, ask us for the matching Rittal earthing parts.
Are the bonding wires included?
No. The rail comes with its connection screws, isolators and two 25 mm² earth connections; the conductors themselves are ordered separately.
Singular Expert Insight · Buyer's Guide
Grounding is often the last thing planned in a new rack and the first thing an electrical inspection checks. A copper earth rail makes every bond visible and easy to test. Browse other
19-inch rack accessories to complete the cabinet.
✓ Buy it if you run a Rittal VX IT or TS IT enclosure 800 mm wide or deep and need a proper central bonding point.
✕ Skip it if your enclosure is 600 mm wide and deep, or it is from another manufacturer.
→ Also consider Rittal earthing straps and bonding kits for doors and side panels, installed by your electrician.
