Fuse link - NH00/WT-00 gF 100A/500V - quick 004114339

Installation and device safety – NH00 fuse links

This NH00/WT-00 gF 100A/500V fuse link is a protective element that safeguards electrical installations against the effects of overloads and short circuits. This is particularly important in industrial environments where the risk of such events is higher. Fuse links of this type are widely used in protecting electrical circuits, ensuring continuity of operation and minimizing the risk of failure.

The fuse link is characterized by a fast response (gF), meaning it reacts quickly to sudden current increases, providing effective protection for sensitive devices. The rated current of 100A at 500V makes it a suitable choice for many industrial applications. A combined (double) blow indicator facilitates identification of a blown fuse, speeding up the repair process and minimizing downtime.

Characteristics and application

NH fuse links are commonly used in industrial installations due to their reliability and effectiveness. The construction based on high-quality steatite provides resistance to environmental conditions and thermal loads. Silver-plated knife contacts guarantee good electrical contact and minimize power losses. This particular model with a gF characteristic is designed to protect circuits requiring fast intervention in the event of short circuits, e.g., circuits powering motors or transformers.

It is worth noting the versatility of NH fuse links – they can be mounted in various types of fuse bases, making it easier to integrate them into existing installations. The use of compact fuse links allows for optimizing space in electrical switchboards and reducing installation costs. Additionally, the stability of the current-time characteristics ensures repeatable operation and full selectivity – i.e., the ability to disconnect only the damaged part of the installation without interrupting the power supply to the remaining circuits.

Construction and special features

The construction of the fuse link is based on a solid body made of high-quality steatite – a material characterized by excellent insulating properties and resistance to high temperatures. The internal fuse element made of copper, precisely matched to the rated current value, provides effective protection against overloads and short circuits. Filling the inside of the body with quartz sand further increases its mechanical and thermal strength. Knife contacts made of copper and brass coated with a layer of silver guarantee low transition resistance and minimize energy losses.
