Connection rail D9XFH3N24 A9XPC724

Universal busbar for Acti9 distribution boards

The D9XFH3N24 busbar is a key element of electrical installations, designed for efficient and safe power distribution in Acti9 systems. Designed for mounting in distribution boards, it allows the connection of up to eight devices (circuit breakers, protection devices) with a 3P+N pole. Its construction provides not only solid connections but also ease of installation and configuration.

Construction and application

Made of high-quality materials, this busbar is characterized by durability and reliability. The ability to cut to size allows it to be adapted to the specific needs of the installation, minimizing material waste and simplifying the assembly process. The busbar is designed to work with devices equipped with a neutral conductor (N) and phases (L1, L2, L3), making it a versatile solution for various applications. The spacing between terminals of 9 mm facilitates the connection of wires of different thicknesses. The length of the busbar is 491 mm, and the width is 24 modules – allowing for optimal use of space in the distribution board.

Safety and compliance with standards

The D9XFH3N24 busbar meets the requirements of IEC 61439-1, guaranteeing safety and compliance with applicable regulations. The rated impulse voltage is 4 kV, and the maximum rated operating voltage Ue is 400 V. The rated continuous current Iu is 80 A, which provides effective protection of the circuit against overload. Additionally, the busbar has insulation and is made of self-extinguishing materials (fire resistance class according to IEC 60695-2-1), which increases safety in the event of a short circuit or fire. The product has a Green Premium label – confirmation of Schneider Electric's commitment to environmental protection and sustainable development.
