NH2C fuse links - the key to a safe electrical installation
NH2C fuse links are an essential element of every professional electrical installation. At Onninen, we offer a wide selection of these key components. Our products guarantee the highest level of protection against overloads and short circuits. They ensure that electrical installations operate safely and reliably.
NH2C fuse links come in various versions. Models with different rated currents and characteristics are available. Our offer includes both industrial delayed and motor fuse links. Each type has its unique application.
Types of NH2C fuse links available at Onninen
Our assortment includes NH2C fuse links from leading manufacturers. We especially recommend products of our own brands: Onnline and FXA. They are characterized by an excellent price-quality ratio. We also offer recognized brands such as Opal or Prof.
- Industrial fuse links, slow-blow, NH2C
- Industrial motor fuse links NH2C
- NH2C inserts with different rated currents (from 25A to 400A)
- NH2C inserts with different rated voltages
Each type of NH2C fuse link has its specific application. Delay fuse links work well in circuits with high starting currents. Motor fuse links protect drive systems. Selecting the right type is crucial for the safety of the installation.
How to choose the right NH2C fuse links?
The correct selection of NH2C fuse links is the basis of a safe electrical installation. In our daily practice, we see how important this issue is. Clients often ask us about selection criteria. Here are the most important parameters to pay attention to:
- Rated current - must be adapted to the circuit load
- Nominal voltage - cannot be lower than the installation voltage
- Time-current characteristic - slow or fast
- Breaking capacity - adequate to potential short circuit currents
- Class gG or aM - depending on the protected circuit
In our experience, the most common mistake is to select inserts with too low a rated current. This leads to unnecessary trips. On the other hand, too high a rated current will not provide effective protection. That is why it is so important to select the parameters precisely.
Many customers ask us about the differences between gG and aM inserts. gG inserts are universal protections for protecting cables. aM inserts are dedicated to protecting electric motors. Their characteristics include high starting currents.
Practical applications of NH2C fuse links
NH2C fuse links are widely used in industry and energy. Recently, in a project for a large production plant, we used them to protect technological lines. NH2C inserts protected both power and control circuits.
In the case of modernization of electrical switchboards, we most often use NH2C inserts with rated currents of 100-250A. They provide optimal protection for typical industrial installations. For larger receivers, such as electric furnaces, we reach for 400A inserts.
Onninen recommends using NH2C fuse links in ATS systems (Automatic Transfer Switch). Their high breaking capacity guarantees safety when switching power. This is crucial in facilities that require continuity of power supply, such as hospitals or data centers.
In our practice, we often encounter the challenge of selecting protection for soft-start systems. In such cases, NH2C inserts with aM characteristics are useful. They allow safe starting of engines, eliminating the risk of unnecessary shutdowns.
NH2C fuse links are also suitable for photovoltaic installations. They protect panel strings and inverters. Their high breaking capacity is crucial for potential short circuits in DC systems.
Our experience shows that NH2C inserts are irreplaceable in the main switchboards of buildings. They provide selectivity of protection, which is crucial for the continuity of power supply. In the event of a failure, they only disconnect the damaged circuit, leaving the rest of the installation under voltage.
NH2C fuse links are not only a protection but also a diagnostic element. Their burnout often signals problems in the installation. Analysis of the nature of the damage to the insert allows identifying the cause of the failure. This is a valuable tool for maintenance services.
At Onninen, we offer not only fuse inserts, but also complete solutions. We supply fuse bases, disconnectors and mounting accessories. This allows our customers to implement all protection within a single order.
Our company provides full technical support in the selection of NH2C inserts. Our specialists will help you analyze the installation and select the optimal protection. Thanks to this, you can be sure that the selected solution will be effective and economical.
We encourage you to contact our technical department to select the optimal NH2C fuse links for your installation. Our experts will be happy to answer all your questions and help you choose the best solution.
