Terminal Blocks - Barrier Blocks

Barrier blocks are a type of terminal blocks which are used to bridge two conductive materials together, while isolating one from another. Typically, they are used in electrical power supplies, DC motors, automotive engines, and other applications requiring stable current supply and lasting connections.

Barrier blocks typically consist of two contacts, which are connected via a barrier. One contact carries the working current; the other carries the ground current. The barrier helps prevent short-circuits by preventing the working current from passing too rapidly between the two contacts. This makes barrier blocks an essential component in applications that require consistent, reliable power transfer.

Barrier blocks are designed to provide protection for electrical components from short-circuits, overvoltage, and overcurrent. This protection is necessary to ensure that the electrical equipment is not damaged during operation or in the event of an unforeseen fault.

The primary feature of barrier blocks is their built-in insulation, which prevents the current from traveling through parts of the circuit that are not intended to be connected. This helps reduce the risk of electrical shock and also extends the life of the wire and other components of the circuit.

Barrier blocks come in a variety of sizes and shapes to accommodate a range of applications. They are available in both single and dual-pole versions, which can be used in parallel or series. This makes them ideal for a variety of applications, such as DC motors, automotive engines, transformers, and other applications requiring stable current supply. Their design also makes them particularly well-suited for DC circuits.

When selecting a barrier block, it is important to consider the application’s electrical requirements. This includes the voltage and current ratings, the type of power supply, the type of insulation, and other factors. Once these requirements have been determined, it is then possible to select a barrier block that meets these requirements and offers the best performance for the application.

Barrier blocks are becoming increasingly popular in a variety of 18-140 applications, due to their dependability, versatility, and safety. They are used in everything from commercial and residential power supplies to automotive engines, aeronautical applications, and more. Barrier blocks provide reliable current transfer, extended service life, and a low-risk of electrical shock.
