Terminal blocks, nowadays, are special kind of connectors in electrical industries, used for two or more wires making electrical contact. Basically, they are divided into two parts - Barrier Blocks and Non-barrier Blocks. 0387110403 terminal blocks belong to the Barrier Blocks category.

Barrier blocks are ‘terminal boards’ which use barriers to isolate short circuit shunts. They are commonly used in controlling ad monitoring instruments and equipment, as it can easily and accurately connect multiple wires in order to make sure the wiring system is properly completed. Their secure connection of wires makes it easy and convenient for unwanted currents bypassing and prevents electrical short-circuiting in the wiring system.

Basically, 0387110403 terminal blocks consist of a block body (the main body), enclosing a coil spring (for maintaining the electrical contact of the connecting wires), a screw hole (for fixing the terminal block to the case) and a series of connecting holes in the block body. The number of connecting holes depends on the number of wires are to be connected to the terminal block.

Therefore, the application field includes powering and controlling circuits for microprocessors, relay coils, miniaturizing electronic circuits, monitoring and controlling instruments. Furthermore, the use of such terminal blocks is not limited to the industrial domain only, nowadays, their uses are widely extended to residential electronics.

As for the working principle of the terminal blocks (regardless to the model / type of terminal blocks), it depends on the basic principles of electricity which states that electricity flows in an unbroken electrical circuit system. The electrical flow passes through a circuit in an unidirectional manner, from the live (positive) wire to the neutral (negative) wire. Wherever there is a break in the circuit, the electrical flow stops and so does the flow of electricity.

When the 0387110403 terminal blocks come into the scene, the circuit remains unbroken. The two parts of a terminal block (the positive and negative ends) can be connected easily and securely. Thus, the current flow in the circuit can move on uninterrupted, ensuring that there is no sudden and unexpected surge of electricity.

To conclude, instead of using a solder or a crimp, terminal blocks are used to secure the ends of wires together, while keeping the wires separate from each other. This separate connection makes it possible to easily access and disconnect any one of the wires without the need to disconnect all the wires in the system. 0387110403 terminal blocks, belonging to the Barrier Blocks family, provides a safe and secure connection in the wiring system.
