Circuit breakers and modular disconnectors

Modular switches and disconnectors - key elements of electrical installations

Modular circuit breakers and disconnectors are the foundation of safe and reliable electrical installations.   In our daily practice, we see how important these components are. They provide protection, control and flexibility in managing electrical circuits. Our offer includes a wide range of products from leading brands.

The range includes devices from renowned manufacturers. These include Eaton, Hager, Eti, Legrand and Schneider Electric. Each of these companies is renowned for its innovative solutions and reliability.   Our experience shows that the products of these brands meet the highest quality and safety standards.

Types of modular circuit breakers and disconnectors in the Onninen offer

Our extensive range includes various types of devices. These include:

• Modular network-generator switches
• Isolating switches
• Main isolating switches
• Switches with light
• Rotary switches

Additionally, we offer switch disconnectors in 1-, 2-, 3- and 4-pole versions.   This diversity allows for precise matching of devices to the specific needs of the installation.   Many customers ask us about the differences between these types. Each has its own unique uses and features.

Modular network-generator switches are used in emergency power supply systems. They enable efficient switching between the network and the generator. Isolating switches, in turn, are used to safely disconnect circuits. This is crucial during maintenance work.

Criteria for selecting modular circuit breakers and disconnectors

Selecting the appropriate circuit breaker or disconnector is a key decision for installation safety.   In our daily practice, we advise clients on how to make the right choice. The main criteria to consider are:

• Nominal voltage
• Rated current
• Number of poles
• Short-circuit capacity
• Trigger Characteristics

The rated voltage must correspond to the installation voltage. The rated current should be adapted to the circuit load. The number of poles depends on the type of installation - single-phase or three-phase. The short-circuit capacity determines the maximum short-circuit current that the device can safely interrupt.

The tripping characteristic is important to ensure protection selectivity.   Our experience shows that the proper selection of these parameters significantly affects the reliability of the entire installation.   An inappropriate selection can lead to overloading or insufficient protection.

Practical applications of modular circuit breakers and disconnectors

In our daily work, we encounter various scenarios of application of these devices. Recently, in a project for a large shopping center, we used 4-pole isolating switches. This allowed for safe disconnection of individual sections of the installation during maintenance work.

In the case of the office building modernization, we used switches with a light. This allowed for easy identification of active circuits.   This solution significantly improved the management of the building's electrical installation.   Customers often appreciate such practical amenities.

Modular network-generator switches were used in the hospital. They ensured reliable switching to emergency power at critical moments. In industry, main isolating switches are necessary for safe disconnection of production machines.

Our company provides comprehensive support in the selection and installation of these devices.   We offer not only products, but also expert advice. Our experts will help you choose the optimal solutions for each installation. We also provide training in the field of proper assembly and operation.

At Onninen, we focus on innovation and quality. That is why we regularly update our offer with the latest solutions. We follow market and technological trends. This allows us to offer products that meet current needs and standards.

We often come across questions about the energy efficiency of these devices. It is worth emphasizing that modern modular switches and disconnectors contribute to the optimization of energy consumption. Precise control of circuits allows for effective energy management in buildings.

Our experience shows that investing in high-quality modular circuit breakers and disconnectors pays off quickly.   This translates into increased safety, installation reliability and reduced operating costs. These are key aspects for every professional electrician and investor.

Onninen especially recommends solutions that combine functionality with ease of installation. Products such as rotary switches or 3-pole isolating switches are highly regarded by installers. Their ergonomic design streamlines work and minimizes the risk of installation errors.

When modernizing older installations, we often recommend replacing outdated switches with modern models. This allows for a significant improvement in the safety and functionality of the entire electrical installation. This is particularly important in public buildings and industrial facilities.
