Cable rail clamps

Cable rail clamps - essential elements of electrical installations

Cable rail clamps are key components in electrical power distribution systems.   They are used to securely attach cables to busbars. At Onninen we offer a wide range of top quality terminals. Our products meet strict safety standards. They guarantee reliable electrical connections in a variety of applications.

We often come across questions about selecting the right terminals. Customers are looking for solutions for specific projects. That is why our offer includes terminals for various wire cross-sections. Single-screw and multi-screw models are available. We also have terminals for connecting aluminum and copper wires.

Types of cable rail clamps available at Onninen

Our assortment includes several main types of clamps:

• Screw terminals - the most popular and universal type
• Spring terminals - ensuring constant pressure on the wire
• Screwless terminals - for quick assembly
• Multi-level terminals - for connecting several wires at the same time

Our experience shows that selecting the right clamp for a specific application is crucial.   The following should be taken into account: the cross-section of the conductor, the material of the rail and the working conditions. In the case of installations exposed to vibrations, we recommend spring terminals. Screw terminals with a spring washer are suitable for LV switchboards.

Many customers ask us about terminals for aluminum wires. Here we recommend special bimetal terminals. They prevent electrochemical corrosion at the copper-aluminum interface. Our offer also includes EB grounding strips. They are used to equalize potentials in installations.

Our brands of cable rail clamps

At Onninen, we focus on proven solutions from renowned manufacturers. At the same time, we offer high quality at affordable prices. That is why our range includes our own brand clamps:

• Onnline - our flagship brand, combining quality and economy
• Fxa - products for industrial applications
• Opal - terminals for everyday electrical installations

Our own brands are a guarantee of reliability confirmed by many years of experience.   These products undergo rigorous quality tests. They meet all required safety standards. At the same time, we offer them at attractive prices. This is the optimal solution for installation companies and industry.

In everyday practice, we see how important it is to select the right clamps. We recently used Fxa clamps in a project for a large production plant. The customer needed a solution that was resistant to vibrations and high temperatures. The Fxa spring clamps proved to be ideal in these conditions. They ensured a stable connection even under heavy loads.

Criteria for selecting cable rail terminals

When selecting the right clamps there are several key factors to consider:

1. The cross-section and material of the wire - this is the basic selection criterion. The clamp must be matched to the diameter of the wire. For aluminum wires, we use special bimetal clamps.

2. Rated current - the terminal must withstand the maximum current flowing in the circuit. It is worth considering the reserve, especially in industrial installations.

3. Operating voltage - terminals must have an appropriate insulation class. In high-voltage installations, we use terminals with reinforced insulation.

4. Environmental conditions - in places exposed to moisture or chemicals, we choose corrosion-resistant clamps. For outdoor applications, we recommend clamps with anti-corrosion coating.

5. Mounting method - we take into account access to the installation site. In tight switchboards, screwless or angle terminals will work well.

Our experience shows that the correct selection of terminals translates into failure-free operation of the installation.   In case of doubt, it is worth consulting our specialists. We will help you choose the optimal solution for a specific application.

In the case of office reorganization, we most often encounter the need for flexible solutions. This is where floor terminals come in handy, allowing for easy changes in cabling. For clients in the construction industry, we recommend screwless terminals. They allow for quick assembly, which is crucial when schedules are tight.

Onninen recommends using comprehensive solutions. In addition to clamps, we offer a full range of assembly accessories. These include markers, insulating sleeves and specialist tools. This approach guarantees the compatibility of all installation elements.

In our daily practice, we see a growing interest in intelligent energy management systems. That is why we also offer terminals with a current measurement function. They enable monitoring the load of individual circuits. This is a valuable solution for companies striving to optimize energy consumption.

Cable rail clamps are the basis of a safe and reliable electrical installation.   At Onninen, we provide comprehensive support in their selection and application. Our experts provide professional advice at every stage of the project implementation. We invite you to contact us and take advantage of our many years of experience in the electrical industry.
