Terminal Blocks - Barrier Blocks

The 39400-0305 is a terminal block type that functions as a type of barrier block in various electrical applications. This type is designed as an insulation displacement contact (IDC) that is a factory-assembled access point. By using an IDC, electrical integration is made possible through a simple and efficient connection process.

Application Field

Barrier blocks like the 39400-0305 can be found across many different industries and can be used to either provide a connection between existing wiring or to help protect existing wiring from potential damage. This terminal block type is often found in higher voltage applications and is popularly used in the automotive sector, digital meter communications, solar panel applications and various military-grade operations.

Working Principle

The basic working principle of terminal blocks is very simple. These block types make use of a prewired IDC contact connector that is pressed into the insulation of the wires, allowing for a secure connection without needing to strip the insulation away. This is especially useful in higher current levels and makes the connection process much faster and easier.

The 39400-0305 block type is unique in that it has a special slide actuator that needs to be opened in order to gain access to the IDC. This provides a greater level of protection and security for the wires as it helps prevent accidental damage or short circuits. The block is mounted in such a way that pressing in the actuator pins closes the circuit allowing for safe and secure connection of the wires.

Once all the wires are in place the terminal is ready to be used, though it should always be checked for any loose connections. The user should also make sure that all the IDC pins are correctly seated as any loose wires can potentially create dangerous short circuits or cause over-temperature issues in the long run.

Terminal blocks such as the 39400-0305 provide a highly efficient and secure way of creating power connections in various applications. These block types are designed for easy installation and are resistant to corrosion, vibrations and extreme temperatures. Additionally, these terminal blocks provide a secure connection that is resistant to accidental disconnections and short circuits.
