EDB distribution blocks are used as connecting elements for neutral conductors “N”, grounding conductors “PE”, and outgoing lines in low-voltage distribution panels. They ensure reliable and safe installation thanks to their insulated design and transparent protective cover.
EDB blocks are available in 2-pole and 4-pole versions with varying numbers of terminals. Each busbar is insulated, and the ability to mount them on both a TN35 DIN rail and a mounting panel makes these blocks a versatile solution for electrical panels.
Key Benefits
- Versatility: 2-pole and 4-pole versions.
- Safety: transparent cover for protection and visual inspection.
- Installation flexibility: mounting on a DIN rail or mounting panel.
- Reliability: each busbar is isolated; connection with or without terminals is permitted.
- High resistance: dynamic short-circuit current withstand capacity up to 20 kA.
Model variants
- EDB-207: 2p, L+PE/N, 125 A
- EDB-211: 2p, increased number of terminals, 125 A
- EDB-215: 2p, increased number of connections, 125 A
- EDB-407: 4p, 3L+PE/N, 125 A
- EDB-411: 4p, extended version, 125 A
- EDB-415: 4p, increased number of connections, 125 A
- EDB-413-160A: 4p, 3L+PE/N, up to 160 A
