Overview

The Mersen T1023425 NH-vertical fuse rail BSL (Size NH00) is a high-performance 3-pole bus bar system designed for 690VAC applications at 160A. Engineered for direct installation onto 100mm bus bar systems, this modular fuse rail system provides touch-protected IP20 safety while enabling fast, tool-free installation and maintenance. The system is compliant with IEC/EN 60269-2 and VDE 0636-2 standards, ensuring compatibility with NH fuse-links in Size 00 configurations. Key features include Al/Cu clamps for versatile cable connections (1.5-70 mm²), integrated cover shrouds for IP20 protection, and a modular design that allows individual component installation. The T1023425 supports cable termination options including M8 terminal screws, clamp straps (Cu 4-70 mm²), and V-terminal clamps (35-240 mm²), providing flexibility for various wiring configurations. With a package weight of 0.84 kg and dimensions optimized for 100mm bus bar systems, this fuse rail delivers reliable short-circuit protection up to 80 kA. Ideal for industrial switchgear, feeder pillars, and distribution boards, the BSL NH-vertical fuse rail system reduces installation time by 30-40% compared to traditional methods while maintaining high dielectric strength and thermal stability. The touch-safe design eliminates exposed live parts during maintenance, enhancing operator safety in high-current applications. Compatible with Mersen NH fuse-links (e.g., NH1AM69V160P-2), this system ensures consistent performance across voltage ranges from 500V to 690VAC.
