Horizontal forked comb busbar L1L2L3N L1N L2N L3N L2N 12 mm2 80A 12M KDN450D

Fork-type comb busbar – a practical solution for three-phase distribution boards

This product is designed for three-phase installations with a neutral conductor (3 P + N) and enables simultaneous connection of up to four devices. With a width of 12 modules and a length of 210 mm, the busbar fits perfectly into standard compact distribution boards. The construction is made in grey color and features insulation, enhancing operational safety at a maximum current of 80 A and a conductor cross-section of 16 mm². Impulse voltage resistance up to 4 kV and a rated working voltage of 400 V meet the requirements of modern power systems.

Features and applications

• Compatibility with N rails – the busbar can be used in systems equipped with a neutral rail, simplifying distribution board design.
• Wide fork spacing (17.8 mm) ensures convenient conductor mounting and minimizes the risk of mechanical damage.
• Four poles allow simultaneous connection of phases and the neutral conductor within a single unit.
• Designed for devices with main power supply, but does not support auxiliary contacts – eliminating unnecessary complications in simple installations.
• Thanks to insulation, components are protected against accidental contact and moisture, increasing the durability of the entire system.

Benefits for the installer and end user

• Quick installation – the simple fork-type system allows rapid conductor connection without the need for additional tools.
• Operational safety – high surge resistance (4 kV) and robust insulation reduce the risk of short circuits and equipment damage.
• Expansion flexibility – the ability to connect up to four loads in one location facilitates future installation modifications.
• Aesthetics and order – uniform grey housing and precise fork placement ensure a tidy appearance of the distribution board.
• Compliance with European standards – meets requirements for impulse voltage and rated operating voltage, guaranteeing the legality and reliability of the installation.

The 12 M fork-type comb busbar is a practical component of every modern distribution board, combining ease of installation with high resistance to operating conditions.
