Hager KDN363A 3P phase busbar 10 mm², 12M

Hager KDN363A is an insulated phase busbar designed for distributing power between modular devices in three-phase distribution boards. It is used in residential, commercial, and light industrial electrical installations where several modular devices need to be connected in a compact and orderly way. Instead of individual jumpers, the busbar provides a structured connection solution for group wiring in switchboards. The product has 3 poles and is intended for 3 phases, making it suitable for three-phase circuits. Its nominal continuous current is 63 A, while the maximum rated operational voltage reaches 400 V. The conductor cross-section is 10 mm², which corresponds to typical requirements for modular switchboard distribution within the specified current range. The busbar is insulated, which helps reduce the risk of accidental contact with live parts during installation and service work. Electrical connection is made through a fork-type interface, allowing straightforward engagement with compatible terminal designs on modular apparatus. The busbar is suitable for 4 devices and is not intended for devices with an auxiliary switch or for devices with an N conductor. This makes it a solution focused specifically on phase distribution in compatible modular assemblies. The overall length is 210 mm, the module width is 17.8 mm, and the width corresponds to 12 module pitches. These dimensions help integrate the busbar into standard modular enclosures with limited space. If necessary, the product can be cut to size, which simplifies adaptation to different board layouts and assembly schemes. The gray color supports clear visual identification inside the enclosure and fits typical distribution board layouts. The busbar also has an impulse withstand voltage of 4.5 kV, indicating its ability to tolerate short-term overvoltage events that may occur in low-voltage networks. With its insulated construction, fork connection, and dimensions designed for modular installation, this Hager busbar is a practical component for organizing three-phase power distribution in switchboards where installation speed and connection consistency matter.
