Overview

The Mersen J226719 NH0 3-pole fuse base is a high-performance industrial component designed for IEC NH fuse systems, delivering reliable circuit protection in low-voltage applications. Engineered for 1000V AC/DC operation, this DIN rail-mounted fuse base supports a continuous current rating of 160A, making it ideal for power distribution, motor control centers, and renewable energy systems. The plastic base ensures lightweight durability while maintaining IP20 indirect touch protection for enhanced safety in industrial environments. Key technical features include stable silver-plated electrolytic copper contact springs with captive steel springing for thermal stress resistance, rated impulse withstand voltage of 6kV (size 00) or 8kV (sizes 0-4), and compatibility with NH fuse-links featuring 8mm contact blades. The three-pole design allows for parallel mounting in compact configurations, with each unit supplied with phase partition walls for electrical isolation. Screw-type connections provide secure termination for conductors up to 25-300mm² (with appropriate lugs), while the DIN rail mounting system enables rapid installation and maintenance access. This fuse base is particularly suited for applications requiring high interrupting capacity and precise fault protection, including photovoltaic installations, industrial machinery, and utility power distribution. The J226719 meets IEC 60269-1/-2 standards and NF EN 60269-1 compliance, ensuring global compatibility with NH fuse systems. For systems requiring fault signaling, microswitch options are available (250VAC/10A) when used with striker-equipped fuse-links. The compact NH0 size optimizes panel space while maintaining robust performance in harsh electrical environments.
