Rails and bridging blocks

Rails and bridging blocks - essential elements of electrical installations

In our daily practice we see how important a role busbars and bridging blocks play in modern electrical installations.   These inconspicuous components are a key element of the power distribution system . They ensure efficient and safe distribution of power in switchboards. Our customers appreciate their versatility and reliability.

We offer a wide range of rails and bridging blocks from renowned brands. Among them are products from companies such as Eaton, Schneider Electric, Hager and ETI. Each of these brands has its own specifics and advantages. Our consultants will be happy to help you choose the optimal solution.

Types of rails and bridging blocks available in our offer

Our range includes various types of rails and bridging blocks. These include:

• Insulated busbars
• Single-phase and three-phase current rails
• Three-phase bridge blocks
• Rails for connecting modular equipment
• Pin and fork rails
• 3-phase power rails
• Connecting bridges for surge arresters

Each of these products has its own unique application and characteristics . Insulated busbars are suitable for compact switchboards. Single- and three-phase current buses enable efficient power distribution. Three-phase bridge blocks facilitate the connection of circuits in industrial installations.

Recently, in a project for a large shopping center, we used EVG modular equipment connection rails. This solution allowed for significant space savings in the switchboard. At the same time, it ensured a reliable connection of all system elements. The customer was very pleased with the final effect.

Criteria for selecting rails and bridging blocks

Selecting the appropriate rails and bridging blocks requires taking many factors into consideration.   The most important of them are current capacity, rated voltage and environmental conditions . Dimensions and compatibility with other elements of the installation are also important. Our specialists always advise, taking into account the specifics of a given project.

When modernizing older installations, we often encounter the challenge of selecting rails. They must fit the existing infrastructure. At the same time, they should meet current safety standards. In such situations, universal pin and fork rails prove their worth. They provide flexible assembly and high reliability.

When selecting rails and bridging blocks, it is worth paying attention to:

1. Maximum rated current of the installation
2. Required IP protection class
3. Short circuit resistance
4. Future system expansion possibilities
5. Easy to install and service

Properly selected rails and bridging blocks guarantee the safety and reliability of the entire electrical installation . They also affect the energy efficiency of the system. In our practice, we see how important it is to approach each project individually.

Innovations in rails and bridging blocks

The electrical industry is constantly evolving, and with it, rails and bridging blocks are evolving. Modern solutions offer increasingly higher current-carrying capacity. At the same time, they are becoming more compact and easier to install. Among the innovations, it is worth mentioning rails with built-in surge protection.

An interesting trend is also rails made of alternative materials. Products made of oxygen-free copper or aluminum alloys are becoming more common. These materials provide excellent conductivity with less weight. This is especially important in the case of large industrial installations.

At Onninen, we follow the latest trends and regularly update our offer. This ensures that our customers always have access to the latest solutions.   We focus on products that not only meet current standards, but often exceed them . This is a guarantee of safety and long-term reliability of the installation.

Our experience shows that investing in high-quality rails and bridging blocks always pays off. It translates into lower energy losses and fewer failures. In the long run, this means significant savings for our customers.

Many customers ask us about the possibilities of modernizing existing installations. In such cases, we often recommend HOME series modular equipment connection rails. They are compatible with most popular switchboards. They allow for quick and safe system updates without having to replace the entire infrastructure.

Busbars and bridging blocks are not only technical elements, but also the key to effective energy management . In an era of rising electricity costs, their role is becoming increasingly important. A well-designed power distribution system can significantly reduce energy bills.

At Onninen we offer not only products but also comprehensive advice. Our experts will help you choose the optimal solutions for each project. We invite you to contact us and take advantage of our many years of experience in the electrical industry.
