1861167 application field and working principle

Terminal blocks - panel mount, also known as terminal boards, terminal strip or connector strip, offer effective, reliable and safe connections for electrical and electronic applications. They are commonly used to avoid breaks in continuity and to allow for isolated disconnection of circuits. By providing electrical and mechanical connections, the terminal blocks also guarantee galvanic isolation and current-carrying duties.The main application fields of terminal blocks are in railway, shipbuilding, communications, power supplies and motor control. In addition, they are often used in industrial electronics for connecting components to terminal boards and control systems.When mounted on a panel, the current-of-contact of the terminal block is essentially unaffected by temperature variations, as these are relatively limited because of the panel\'s good thermal conductivity characteristics. Even in heavily loaded currents and in vibration-prone environments, the mounted terminal block will not fail. This makes them very suitable for installation in industry and industrial automation applications.Working principle of the panel-mounted terminal block is relatively simple. The terminals of the terminal block are connected to the power source (be it a battery, AC power or DC power) and to the electrical load using wires. The terminals of the terminal block are usually either in screws, terminal points, terminal strips or plates.When the current flows through the terminal points, an electrical connection will be established and the wires will be securely connected to the terminal points. This provides the connection between the power source and the load, allowing current to flow through the device.One of the main advantages of the terminal block is its ability to offer isolated disconnection for the load from the power source. In case of a short circuit, the current will be isolated and will not flow to the load. The power supply may then be disconnected from the load, thus preventing the fault from occurring.Another advantage of the terminal blocks is their low voltage drop. The electrical connection is much tighter when compared to conventional wiring, which leads to lower voltage drops in the power connections. This helps in improving the efficiency and safety of the electrical system.In conclusion, terminal blocks - panel mount offer an effective, reliable and safe connection between the power source and the load. The advantages of the terminal blocks include their high current-carrying capability and their ability to provide isolated disconnection.
