Comb busbar, 2P, 80A 28 modules BIS2-3PN-56 404950

Professional solution for modular distribution boards

The horizontal comb busbar is a key element of distribution systems, enabling efficient power supply to groups of devices in three-phase installations. The product has been designed with maximum mounting flexibility in mind while maintaining the highest standards of electrical safety.

Construction and electrical parameters

The busbar is made of high-quality conductive materials with a cross-section of 16mm², which guarantees optimal current conductivity up to 80A at an operating voltage of 400V. The two-pole design has been specially balanced for three-phase systems, ensuring even load distribution between phases.

The product dimensions are 1 meter in length with a width corresponding to 28 modules (width expressed by the number of modules), allowing for the connection of a maximum of 28 devices. The spacing between connection points is 17,8mm, standard for modular distribution boards.

Safety and regulatory compliance

The busbar features full insulation and high resistance to environmental conditions. The rated impulse withstand voltage is 2kV, and the short-circuit strength reaches 1,2kA (Icw), providing effective protection against the effects of electrical faults. The rated conditional short-circuit current IQ reaches a value of 0,63kA.

The product operates in a wide temperature range: during installation and operation from -20°C to +50°C, and during storage from -40°C to +70°C. The busbar meets the requirements of European safety standards and holds certificates of conformity.

Mounting flexibility and application

A key feature is the possibility of cutting to size, which allows for a perfect fit to a specific distribution board without the need for additional connecting elements. The busbar is adapted for devices equipped with a neutral conductor (N), enabling the creation of complete power supply systems.

Thanks to its compact design with a height of 30mm, the busbar provides significant space savings in the distribution board while maintaining full functionality for powering multiple circuits. The grey color is the standard solution for this type of electrical installation.
