15kA circuit breakers - the key to a safe electrical installation

15kA circuit breakers are basic elements of modern electrical systems.   Their role in ensuring safety is invaluable. At Onninen, we offer a wide selection of these devices. Our range includes products from renowned brands. These are mainly Eaton and Hager. Thanks to them, electrical installations gain reliable protection.

We often come across questions about the selection of circuit breakers. Customers want to know how to choose the right model. The breaking capacity of 15 kA is an important parameter. It means the maximum short-circuit current that the circuit breaker can interrupt. This is crucial for the safety of the entire installation. Circuit breakers with this characteristic work well in many applications.

Types of 15kA circuit breakers available in our offer

Our range includes various types of breakers. We offer single-, two- and three-pole models. Each has its own application. Single-pole breakers protect single circuits. Two-pole breakers are used in single-phase installations. Three-pole breakers protect three-phase systems.

Our experience shows that selecting the right switch is crucial.   That is why we offer products with different current-time characteristics. These are types B, C and D. Type B reacts the fastest. It is used to protect sensitive devices. Type C is universal. It works well in most home and industrial applications. Type D has the slowest characteristic. It is ideal for protecting circuits with high inrush currents.

• Single-pole circuit breakers 15kA
• 15kA double-pole circuit breakers
• Three-pole circuit breakers 15kA
• Models with characteristics B, C and D

In everyday practice, we see how important the right configuration is. Recently, we used 15kA circuit breakers in a project for a large office building. They provided optimal protection for a complex installation. The client appreciated our recommendation. Thanks to it, he avoided potential problems in the future.

Criteria for selecting 15kA circuit breakers

Choosing the right circuit breaker requires analyzing several factors. First of all, you need to determine the rated current of the circuit. This determines the selection of the circuit breaker. Another aspect is the type of device being protected. Different protection is used for lighting, different for motors. Selectivity of protection is also important. The point is that only the circuit breaker closest to the fault location will trip.

Onninen recommends paying attention to the technical parameters of the switches.   In addition to the rated current and breaking capacity, the following are important:

• Nominal voltage
• Number of poles
• Current-time characteristic
• Energy Limitation Class

In the case of office reorganization, it is most often necessary to change the protections. 15kA circuit breakers work great in such cases. They provide adequate protection for new load systems. Their use guarantees the safety and reliability of the installation.

Many customers ask us about the compatibility of switches with other elements. Our offer also includes mounting rails. They are necessary for the correct installation of switches. We also offer a wide range of accessories. These include auxiliary contacts and shunt releases. Thanks to them, the functionality of switches can be expanded.

Our experience shows that the proper selection of switches is the basis of safety.   That is why at Onninen we focus on comprehensive consulting. We help our clients choose the optimal solutions. We base our recommendations on many years of experience. Thanks to this, our clients can be sure that their installations are well protected.

In everyday practice, we often come across questions about other protections. 15kA overcurrent circuit breakers are not the only protective elements. Our offer also includes straight-through and inclined valves. They are used to regulate the flow in hydraulic installations. We also offer bellows gas meters. They are necessary for measuring gas consumption.

For customers looking for comprehensive solutions, we have a wide range of products. These include hydrophores, inclined gas filters and coalescing separators. Our range also includes external hydrants. All these elements create a coherent system of safety and control.

15kA circuit breakers are a key element of modern electrical installations.   Their correct selection and installation guarantee the safety of users. At Onninen we offer not only products, but also professional advice. Thanks to this, our customers can be sure that their installations are in good hands. We invite you to contact us and take advantage of our offer.
