Terminal blocks are electrical components used to terminate and connect electrical circuits. They are available in a wide variety of sizes and styles with different features to meet the demands of different applications. The A21931800 is a type of terminal block known as a "barrier block".Barrier blocks are used as a form of electrical interconnection. They are often found connecting the wiring harness of an appliance or other electrical system with the printed circuit boards of a product. This type of terminal block has an insulating barrier between the wires and the electrical components which prevents the current from arcing and creating an electrical short.The A21931800 is a single-positional barrier block which has 17 terminals spaced 0.2 inches apart. The terminals are made from phosphor bronze and are fully plated with tin for maximum conductivity. The A21931800 is made from high-temperature, flame-resistant ABS plastic and is rated to UL 94-V-0 and UL 94-V-2. The A21931800 is designed to be used in a variety of applications, such as controlling the power supply of electronic components in heavy machinery and equipment, as a voltage regulator and as a grounding terminal. It is also widely used in medical devices and systems that require multiple connections.The working principle of a barrier block is to divide a specific power supply and voltage range in order to appropriately supply power to different circuits. One side of the block is connected to the line voltage while the other is connected to the load. The barrier ensures the voltage on each side of the block is kept at the correct level and prevents arcing. The current carrying capacity of the A21931800 is 5A. It also has a dielectric strength of 1,000 volts and an insulation resistance of 20 MΩ between each contact point. The terminal block also has grooved entry points that make it easy to connect and insert wires into the block.The A21931800 is available in a variety of colors and can be used with 16 to 18 AWG stranded or solid copper wire. It is often used to connect the wiring harness of an appliance or other electrical system with the printed circuit board. The versatile design and construction of the A21931800 ensures that it can be used in a wide range of applications.
