Terminal Blocks - Barrier Blocks

0387700920 application field and working principle

Terminal blocks and barrier blocks are two of the most common types of electrical connection tools used today to facilitate the automatic connection of electrical components without the need for additional wiring. Terminal blocks provide an economical solution for connecting multiple electrical components, while barrier blocks facilitate the safe, reliable operation of high power electrical systems. This article will explore the application field and working principle of 0387700920 terminal block and barrier blocks in detail.Terminal blocks are used primarily in industrial automation systems for electrical connections. The 0387700920 terminal block is an economical solution that simplifies the wiring of large systems, such as control panels and power supplies. This terminal block has two rows of terminals and a base composed of bars and slotted connectors for easy access. The terminals are connected to a conductor, which is then connected to a circuit board.Terminal blocks are usually placed within the construction of a device and typically contain two types of electrical connection: a conductor bar and a direct connection. The conductor bar is the main electrical connection between the block’s terminals and the circuit board, and typically consists of either a standard PCB connection or an insulation connection. The direct connection, on the other hand, is used to connect the terminals to either a meter or a switch. This connection typically requires additional wire lengths and provides electrical insulation.Barrier blocks, on the other hand, are designed to protect against hazardous levels of voltage and current. These blocks feature a base with two rows, each row consisting of insulated connector pins. The pins allow current to flow from the upper row to the lower row with the help of a barrier that separates them. Barrier blocks provide a simple and effective method of connecting and distributing high current and voltage applications.Barrier blocks come in a variety of sizes with different current ratings (up to 10 or 15 amperes). Most blocks are equipped with an over-current protector, which helps protect the block and associated wiring from current and voltage overloads. In addition, most high current barrier blocks have double insulation that allows them to be used in demanding environments.To summarize, 0387700920 terminal block and barrier blocks are two types of essential electrical connection tools used for various industrial automation systems. Terminal blocks are used to connect multiple electrical components and enable low-voltage direct connections without the need for additional wiring. Barrier blocks, on the other hand, are used to protect against hazardous levels of current and voltage. Through their double insulation, barrier blocks are suitable for use in demanding environments.
