Siemens NH Fuse 50A 500V AC, NH000 Size, High Rupture Capacity, Blade Type, gG Category,

The Siemens 3NA6820 NH Fuse is an industrial-grade circuit protection device built to safeguard electrical systems from overloads and short circuits. Designed for reliability, this fuse offers a current rating of 50 amperes and can operate in systems up to 500V AC. Its NH000 size allows for straightforward integration in compact control panels or switchgear installations, maximizing space efficiency in crowded enclosures.

This model features a blade-type tag for robust connectivity and straightforward replacement when needed. The high rupture capacity ensures the fuse can safely interrupt substantial fault currents, minimizing risk to downstream equipment during electrical faults. Insulated grip tabs further promote safe handling during installation and removal, reducing operator hazards.

Conforming to international safety standards such as VDE 0636, CSA 22.2, and IEC EN 60269, the Siemens 3NA6820 is suitable for line and cable protection applications, reflected by its gG application category. This means it is engineered for selective protection and coordination with other system protection devices, an essential requirement in critical infrastructures like industrial plants, commercial electrical panels, and power distribution systems.

The fuse supports operation within a temperature range from -5°C up to 40°C, ensuring consistent performance in both standard and challenging environments. Typical applications include protection of building service panels, industrial automation lines, and power supplies where high selectivity and fast operation are vital for system integrity.

Part of Siemens' 3NA6 series, these NH fuses with combination sensors provide not only reliable operation but also enhanced safety, making them ideal for use across industrial, manufacturing, and utility sectors. The durable construction and precise manufacturing ensure long service life and minimal maintenance. The integration of insulated grip tabs makes this model user-friendly, especially for electricians adhering to strict safety protocols.
