Horizontal forked comb rail L1NL2NL3N 35 mm2 24 M KDN599B

Horizontal fork‑type comb busbar

The KDN599B comb busbar is a distribution board component designed for separating and joining phase and neutral conductors in low‑voltage installations. It has a capacity of 54 modules — meaning it accommodates 27 L/N pole pairs, each allowing the connection of a single fork‑type connector. The design enables compact and orderly wiring of many circuits without the need for additional linking conductors.

Rigid conductors with a cross‑section of 35 mm² are securely attached via fork‑type connectors — no twisting or screwing of conductors directly to the busbar is required. This reduces the risk of poor contact, simplifies installation, and speeds up service. Rated current is 125 A and rated voltage up to 400 V AC, making the busbar suitable for typical distribution circuits in residential and office construction.

A rated impulse voltage of 4000 V provides surge resistance — important in areas with a high risk of electromagnetic disturbances. The busbar is mounted on a DIN rail, and its length (964 mm) matches standard dimensions of distribution cabinets. Each connection point is clearly labeled (L1, L2, L3, N), eliminating wiring errors.

No special tools are required — a standard screwdriver is sufficient. The product complies with IEC 61439, and the EU Declaration of Conformity confirms adherence to current safety standards. The package contains 5 units — a practical quantity for installers working on larger projects.
