Overview

The Mersen A1002294 NH-vertical fuse rail BSL, specifically sized as NH2, is a robust and reliable component for industrial electrical systems. This 3-pole bus bar system is engineered to operate at a voltage rating of 690VAC and a current carrying capacity of 400A. Its design is optimized for direct integration with 185 mm bus bar systems, facilitating a streamlined installation process. The A1002294 is a key element in providing dependable short-circuit protection within industrial electrical panels. Adherence to stringent industry standards is a hallmark of the BSL series, as it complies with both IEC/EN 60269-2 and VDE 0636-2. This compliance ensures seamless compatibility with NH fuse-links of Size 2, which are rated for 400A. For enhanced operational safety, the system features touch protection, meeting IP20 standards, which effectively prevents accidental contact during both installation and routine maintenance procedures. The modular nature of this fuse rail is a significant advantage, allowing for the individual installation of components. This flexibility supports the creation of customized configurations tailored for various applications, including feeder pillars, switchboards, and distribution boards. Cable termination is made straightforward and secure through the use of M12 bolts and V-terminals, capable of accommodating conductor sizes ranging from 35 to 240 mm² for both copper and aluminum conductors. To further bolster safety and maintain a high level of organization within the electrical enclosure, a range of accessories are available. These include cover shrouds, such as the MZKAB and MZKHO models, and phase barriers like the MZSTW1. The A1002294 has a package weight of 3.8 kg, and its physical dimensions are specifically designed to integrate efficiently with 185 mm bus bar configurations. This makes the A1002294 an excellent choice for demanding industrial applications that require a compact footprint without compromising on high-current handling capabilities, and where strict adherence to safety and compliance regulations is paramount.
