NH4A fuse links - the key to a safe electrical installation

NH4A fuse links are an essential element of every electrical switchboard.   They protect installations against the effects of short circuits and overloads. At Onninen, we offer a wide selection of these products. Our portfolio includes inserts from renowned brands. Among them are Eaton and Hager. We provide solutions for various applications. We serve both small companies and large industrial plants.

NH4A fuse links are distinguished by their high quality of workmanship. They ensure reliable operation at critical moments. Their parameters are crucial for the safety of the installation. Selecting the right type of fuse link is of great importance. It affects the effectiveness of the protection of the entire electrical system.

Types of NH4A fuse links available in our offer

In the Onninen range you will find various types of NH4A inserts. We offer both standard and specialist models. The most popular are:

  • NH4A Blade Fuse Inserts
  • NH4A quick fuse links
  • NH4A inserts with increased strength
  • NH4A inserts for protection of semiconductor systems

Each type of NH4A insert has its own unique properties and applications.   Knife inserts are suitable for main switchboards. Fast models are ideal for protecting electronic systems. Those with increased durability are used in difficult industrial conditions.

Our experience shows that choosing the right insert can be a challenge. That is why we offer professional advice in this area. Our experts will help you choose the optimal solution. They will take into account the specifics of a given installation and the customer's needs.

NH4A fuse link selection criteria

When choosing NH4A inserts, there are several key parameters to consider. The most important are:

  • Rated current
  • Nominal voltage
  • Breaking capacity
  • Time-current characteristic
  • Energy Limitation Class

Correct selection of these parameters guarantees effective protection of the installation.   The rated current must correspond to the load of the protected circuit. The rated voltage should be adapted to the network voltage. The breaking capacity determines the maximum short-circuit current that the fuse link can interrupt.

The time-current characteristic informs about the speed of the fuse link operation. It is crucial for the selectivity of protection. The energy limitation class affects the protection against the effects of short circuits. The lower the class, the better the protection of devices in the circuit.

In our daily practice, we encounter a variety of installations. Each of them requires an individual approach. For example, in a production plant, we used NH4A inserts with high breaking capacity. They ensured safety at high starting currents of machines.

Practical applications of NH4A fuse links

NH4A inserts are widely used in industry and energy. They are often found in:

  • Main switchboards of production plants
  • Transformer stations
  • Power supply systems for large commercial facilities
  • Energy distribution systems in critical infrastructure

Their reliability is crucial for the continuity of production and business processes.   In the event of a failure, the quick operation of the NH4A fuse can protect against serious losses. We recently used Eaton NH4A fuses in a project for a large logistics center. They effectively protected the facility's main switchboard.

NH4A inserts are also suitable for photovoltaic installations. They protect inverters and DC lines from overloads. In one of our recent solar farm projects, we used NH4A Hager inserts. They provided optimal protection in variable operating conditions.

In the case of modernization of older installations, NH4A inserts often replace outdated protections. They improve the safety and reliability of the system. When reorganizing offices, we most often replace entire switchboards. In such cases, we use modern NH4A inserts with better parameters.

NH4A fuse links are not only a protective element.   It is also an important component of the energy management system. Properly selected, they allow for the optimization of power consumption. They reduce energy losses in the installation. In one of the projects for a furniture factory, we used NH4A inserts with monitoring. This allowed for better control of the load on production lines.

Many customers ask us about the durability of NH4A inserts. Our experience shows that when selected correctly, they serve for years. However, it is crucial to regularly check their condition. As part of our service, we offer periodic inspections of switchboards. They also include inspection of fuse inserts.

Onninen recommends using NH4A inserts from renowned manufacturers. They guarantee the highest quality and reliability. In our offer you will find products from the Eaton and Hager brands. These are proven solutions, valued by professionals.

Choosing the right NH4A inserts is an investment in the safety of your installation.   It is worth entrusting this task to specialists. Our technical advisors provide support at every stage of the project. They will help you choose the optimal solutions. They will provide professional assistance with assembly and configuration.
