Terminal Blocks - Barrier Blocks

Barrier blocks, also known as Euro-terminal blocks, are electric components designed to provide connection points for electrical wires. Most barrier blocks use screw terminals, which offer excellent connection transmission and electrical contact. Barrier blocks, which are also known as pitch connectors, come in various designs and configurations such as double level and rope style.

Application Field

Barrier blocks are widely used in a variety of high power electrical applications including power distribution, signal and control circuits, and other related electrical products. Today, they are typically in use in electronic production, automotive electronics, high power electronics, military, and aerospace.

Barrier blocks are also commonly used in industrial automation systems, medical products, lighting fixtures, power supplies, telecommunications, railway equipment, and any other equipment where reliable and secure circuit connections are needed.

Features and Benefits

Barrier blocks are known for their durability and reliability in providing secure and effective connections. The key features and benefits of these components include:

 
• Easy and quick installation: These components are easy to install and save time and labor compared to conventional soldering.
 
• High compliance: Barrier blocks offer high compliance and are fully-certified according to UL, CSA, and VDE standards.
 
• High power rating: They are suitable for applications with high power ratings up to 16A, allowing users to achieve reliable connections in high power applications.
 
• High electrical contact: Screw contact technology guarantees good electrical contact and maximum current transmission.

Working Principle

The working principle of a barrier block is based on the physical principle of contact between two dissimilar metals in the screws and the terminals. When the screws are tightened, contact between the dissimilar metals on the terminals and the screws takes place, thus creating an electrically charged circuit. The contact ensures that power is applied and that power is effectively distributed throughout the electrical circuit.

The screw terminals of the barrier block are also designed to prevent corrosion or other damages to the wires. The solder-free construction enables users to easily replace or repair electrical connections.

Conclusion

Barrier blocks are essential components in many electrical applications today, providing connection points for electrical wires or circuits. Today, barrier blocks come in various designs and configurations to suit different applications. Professionals must select the appropriate kind of barrier block to ensure proper connections for their applications.
