Terminal block is a modular block with an insulated electrical connector that connects two or more wires together to ensure a safe connection between the circuits. It comprises a clamping component and a terminal strip which is the body of the terminal block. The body has a mounting element so that the blocks can be easily mounted and unmounted.
Generally, most of the terminal blocks are modular and mounted on a DIN rail to allow users the flexibility to add on the terminals accordingly. This helps to ensure the connections are secure and wires are well organized.
Terminal blocks can be commonly found in most industrial, commercial, and domestic applications. It is mainly used for industrial power, control, automation, and signal applications where several connections are required at the same time.
