The use of busbar systems with their versatile rail-adaptable connection, switching and installation devices is an ideal and cost-effective electrotechnical enhancement of modern distribution boards thanks to their small footprint, modular design and quick assembly contacts. While legacy power distribution systems come with a variety of liabilities and challenges, busbar systems alleviate these pain points in panel design, engineering, and operation through elevated customization and unique design capabilities. Designed for industrial-grade applications, this cabinet combines structural robustness, flexible internal configuration, and scalable system integration. Complete solutions for AC or DC applications. 3-pole, tool-free mounting, short circuit-resistant up to 65 kA, fully contact hazard-protected and with standard flat copper bars for global use. 60 mm bar centre distance. Copper busbar cabinets and control boxes together form the transmission–control backbone of modern industrial power systems. ABB Z-busbar offering is available for 400A, 630A, 1600A and 2500A, to be used either as TN-C or as TN-S with a protected N-bar. The Z-busbar system is used with InLine XLBM and ZLBM and it has a complete offering. The BUSBAR range, in addition to distribution terminal blocks, consists of flat and shaped busbars in copper and aluminium in order to make distribution system inside QDX boards.
