Terminal Blocks - Barrier Blocks

14004-11 Barrier Blocks are designed with integrated barriers between terminals in order to meet the requirements of applications where there is a need to isolate operating currents. They are widely used in the automotive, communications, medical and industrial areas, where safety and protection from interference are the two most important factors. The 14004-11 Barrier Block is an ideal choice for applications where electrically conductive components need to be separated but still need to be electrically secure.

Application Field

Terminal Blocks with Barrier Blocks are used in applications to avoid interference, protect against persistent current, isolating equipment modules and minimize ground loops. They are widely used in industrial equipment, distribution power systems, medical systems, communication systems, etc. They are suitable for low voltage applications (like 12V DC) and high voltage applications (like 1000V AC).

The most common applications are for avoid interference, especially in industrial applications. In these cases, the use of barrier blocks between connected components ensures that the interference is blocked effectively. This way, the components will not be affected by each other and the system will be more secure and reliable.

In the medical field, barrier blocks are used in applications where electrical equipment needs to be properly isolated to prevent possible hazards. Barrier blocks can be used to separate different components (like monitors, electrodes, etc.) and avoid interference. This way, the safety of medical personnel and patients is increased, as well as the reliability and accuracy of medical tests.

Working Principle

Barrier blocks are designed to have two or more electrically separate areas. Typically, these are the common area and the output area and the terminals are connected in the common area. These areas are separated by a barrier area that is filled with an insulating material, this preventing any current flow between the two terminals or areas. The barrier blocks are typically made from metal, but can also be from plastic.

The terminal blocks with barrier blocks have terminals that are divided into two or more sections. These sections serve as the input and output of the block. The input and output sections are connected by a connecting busbar which ensures that the electricity flows from one terminal to the other. The connecting busbar, when properly installed, also ensures that the power remains at the desired voltage level.

The terminals in the barrier blocks are connected to the source and load by a wiring harness. These wiring harnesses are generally laid out in a way that prevents interference and stress on wires and connectors. The wiring harness can also be made with materials that offer additional protection, like shielded cables.

The barrier blocks are made with safety features that protect users from electric shock if contact is made between terminals. These features are designed in such way that when contact is made, the current automatically turns off an internal enclosure and the power supply is interrupted. This way, the user is protected from any potential harmful interaction with the terminal blocks.

Barrier blocks are an essential element when it comes to connecting electrical components in a secure and safe way. They are used in many electrical applications, from industrial applications to medical systems. By selecting the right type of barrier block, users can ensure that their components will be properly isolated, preventing any interference or harm.
