NH4 fuse links - a key element of electrical installation protection
NH4 fuse links are essential components in electrical protection systems. They provide protection against overloads and short circuits. At Onninen we offer a wide selection of these products. Our range includes industrial fuse links. These include both transformer and time-delay models. Each type has its own unique applications and advantages.
Selecting the right NH4 inserts is crucial for the safety of the installation. Many factors must be taken into account. These include the rated current, time-current characteristic and breaking capacity. In our daily practice, we see how important it is to have the right fit. An incorrect selection can lead to serious consequences.
Types and applications of NH4 fuse links
Onninen's offer includes various types of NH4 inserts. Industrial fuse links - transformer protect transformers against overloads. They are characterized by increased resistance to starting currents. In turn, delayed fuses work well in circuits with high starting currents. They are often used to protect electric motors.
Among the available brands, it is worth mentioning our own brands: Onnline and Fxa. These products combine high quality with an attractive price. In addition to them, we also offer recognized brands of external manufacturers. This provides customers with a wide selection and the ability to adapt to individual needs.

NH4 fuse link selection criteria
When choosing NH4 inserts there are several key parameters to consider. The rated current is the basic criterion for selecting an NH4 fuse link. It must be adapted to the load of the protected circuit. Another important aspect is the time-current characteristic. It determines the time of the fuse link operation depending on the current value.
Breaking capacity is the maximum short-circuit current that the fuse link can safely interrupt. In industrial installations, this parameter is particularly important. The rated voltage of the fuse link must be at least equal to the installation voltage. It is also worth paying attention to power loss. It affects the energy efficiency of the entire system.
At Onninen, we often come across questions about the selection of NH4 inserts. Our specialists are happy to advise on this matter. We help select the optimal solutions for specific applications. This means that customers can be sure that their installations are properly protected.
Practical applications of NH4 fuse links
NH4 inserts are widely used in industry and energy. In large production plants, NH4 inserts protect process lines against the effects of failures. They ensure continuity of production and safety of employees. In the power industry, they are used to protect transformers and transmission lines. They guarantee the stability of electricity supplies.
Recently, we used NH4 inserts in a project for a large logistics center. They protected the main switchboards supplying warehouse automation. Thanks to this, the risk of downtime was minimized. As a result, the customer gained a reliable and safe solution.
In the case of modernization of electrical installations, NH4 inserts are often replaced. This allows the protection to be adapted to new loads. This is especially important when expanding or changing the profile of the company's activity. The correct selection of NH4 inserts then ensures the appropriate level of protection.
- Protection of production lines in factories
- Protection of transformers in power stations
- Protection of automation systems in logistics centers
- Securing installations in public buildings
Our experience shows that regular inspection and replacement of NH4 inserts is essential. This helps to avoid unexpected failures and downtime. At Onninen, we offer not only products, but also expert advice in this area. Our experts will be happy to help you choose the right NH4 inserts.
NH4 fuse links are not only a protective element, but also an investment in the safety and reliability of the installation. Their correct selection and use translates into real benefits for companies. They provide peace and certainty of operation of electrical systems. At Onninen, we make every effort to provide the best solutions in this field.
