Overview

The Mersen BSL NH-vertical fuse rail system (SKU: P1023421) is engineered for robust electrical protection and efficient integration into 185 mm bus bar systems. Designed for triple-pole arrangements, this 3-pole bus bar system accommodates NH fuse-links in accordance with IEC/EN 60269-2 and VDE 0636-2 standards, specifically for Size 00 fuse-links rated at 160A and 690VAC. The BSL system is modular, allowing for straightforward installation of individual components and offering users a high degree of protection during both installation and maintenance procedures. This particular model features touch-protected IP20 design, ensuring operator safety. It is equipped with cable connection clamp straps for secure and reliable conductor termination. The Mersen BSL series provides a dependable solution for power distribution and protection in various industrial applications where NH fuse-links are specified. Its design facilitates fast and easy installation, minimizing downtime and enhancing operational safety. The 185 mm bus bar system compatibility ensures seamless integration with existing infrastructure. This product is manufactured in the US. The vertical mounting orientation of the fuse rail system is specifically designed for efficient space utilization within electrical enclosures. The 3-pole configuration is essential for applications requiring complete isolation of all three phases of a power supply. The use of NH fuse-links, a widely adopted standard in industrial power systems, ensures compatibility with a broad range of protective devices. The 160A current rating signifies its capacity to handle significant electrical loads, while the 690VAC voltage rating indicates its suitability for medium-voltage applications. The IP20 protection level means that the device is protected against solid objects greater than 12.5 mm, and offers no protection against water ingress. The inclusion of clamp strap connectors simplifies the process of connecting power conductors, ensuring a robust and secure electrical connection. The modular nature of the BSL system allows for scalability and customization to meet specific project requirements.
