Terminal blocks, also known as barrier blocks, are electrical connection devices used in an electrical system to control the flow of electric current from one component to another. They provide a secure connection of individual wires, allowing engineers to easily and safely make changes to the electrical system without having to disconnect the entire system or disassemble the components.Terminal blocks can be used in a variety of applications, including in industrial machinery and process control systems, automotive electronics, consumer electronic and home appliance products, and in many other areas. They are used to ensure that electrical currents are uninterruptedly connected to the correct components, which can reduce the risk of short circuits and improve the safety of the electrical systems.Terminal blocks are typically constructed of a base, usually made from square or rectangular non-metallic material, which is designed to hold two or more terminals. These terminals, which are connected to the electric conductors, are fastened with nuts or bolts. The terminals are made from materials such as brass or copper, and are designed to easily clamp down onto the conductors in order to hold the connection securely.When it comes to the working principle, terminal blocks are designed to fall into two categories: the “blocking” type and the “non-blocking” type. The blocking type of terminal blocks uses a fuse or a circuit breaker to protect the electrical components from overloads or short circuits, while the non-blocking type relies on the resistance of the conductor instead.In the “blocking” type of terminal blocks, the current passing through the fuses or circuit breaker is interrupted during an overload or short-circuit event, thereby preventing any further current from flowing. The main advantage of using a blocking type of terminal block is that it can quickly and effectively stop the flow of current in the event of an overload or short circuit.For the “non-blocking” type of terminal blocks, the current is allowed to continue flowing even during an overload or short-circuit event as it is not interrupted by the use of a fuse or circuit breaker. This type of terminal block is most commonly used in systems where continuous monitoring is necessary, such as in industrial systems and process control systems.Terminal blocks are essential components in any electrical system. They provide a secure electrical connection between components, thereby reducing the risk of short circuits and making equipment more reliable and safe. Furthermore, terminal blocks are designed to easily clamp down onto the conductors, making them quick and easy to install and maintain.
