Barrier Blocks

Barrier Blocks, or Terminal Blocks, are widely used in various applications ranging from industrial, automotive, and lighting projects to consumer products of all sizes. Their purpose is to safely contain and protect wires from damage or tampering.

TB400-05

The TB400-05 is a type of Barrier Block that is specifically designed for use in applications with large currents, usually more than 80A. Its unique design allows it to have three levels of vertical fusing, providing an additional layer of protection for the wires. It also features two-way current passing, providing easy access for service engineers to repair or maintain the wiring with minimal effort.

Application Field

The TB400-05 is widely used in various industrial, automotive, and lighting applications. Due to its three-layer protective structure, it is often used in projects requiring a high level of current control. This includes industrial machines such as 3D printers and CNC machines, as well as vehicle electrical systems.

The TB400-05 is also used in many home automation projects. It is especially useful in projects that require both high current control and rapid response due to its ability to provide two-way current passing. This makes it the go-to choice for professionals looking to design smart homes with an emphasis on energy efficiency and safety.

Working Principle

The TB400-05 uses an innovative three-layer protective structure to ensure that wires remain protected from currents of up to 80A. The first layer is a rubberized insulating sleeve, which acts as an insulator to prevent electric shock. The second layer is a set of contact pins which when connected creates the electrical connection between two wires. The third layer consists of a screw system which securely fastens the two wires together.

In addition to the three-layer protection system, the TB400-05 also makes use of two-way current passing. This is accomplished by connecting wires on one side of the block to two contact points facing opposite directions, allowing a current to pass both ways.

These two design features make the TB400-05 an ideal choice for large-scale projects that require a high level of current control. Its unique structure ensures that wires remain safe during operation and can easily be accessed by service engineers if needed.
