Mersen NH0GG50V50 zekeringpatroon gG Gr.0 AC500V 50A sfü combinatie-indicator

NH fuse link engineered for reliable protection of industrial power distribution systems, delivering a breaking capacity of 120 kA at 500 V AC. Its gG utilization category ensures full-range protection for general-purpose applications, safeguarding cables and lines against overloads and short circuits. The combined indicator—front flag and striker pin—provides clear local and remote status signaling, simplifying maintenance and system monitoring.

Advantages

High breaking capacity of 120 kA for superior short-circuit protection. Silver-plated copper contacts ensure low contact resistance and excellent conductivity. Ceramic body offers high mechanical strength and thermal stability. Compliance with IEC 60269 guarantees interoperability and safety. Compact NH size 0 design saves space in distribution boards.
