A21421207 is a terminal block which falls into the category of barrier blocks. It is commonly used in automation, electrical system and other applications that involve making a secure electrical connection. This terminal block is designed for mounting inside an industrial enclosure, making it capable to handle voltage up to 250 VAC/60 VDC and current up to 16 Amps.The primary purpose of a barrier blocks is to provide power to multiple devices while keeping the power separate. This is why these terminal blocks are used in applications such as panel wiring. Services like electric power, control power, short-circuit protection and signal routing can then be distributed using the same terminal block. A21421207 utilizes a barrier design which enables multiple wires to be connected to a single terminal while preventing a short circuit.A barrier block is composed of several parts; the terminal block itself, the contact blades, a busbar and the contact screw. The terminal block and contact blades are connected to the busbar. The contact screw is then used to connect the terminals and contact blades together, making a secure electrical connection.The terminal block, contact blades and screws can be made of various materials, depending on the application and requirements. Materials like steel, copper, phosphor-bronze, beryllium-copper or ceramic can be used. When making a connection, the contact blades are attached to the terminal block and the contact screws are securely tightened together. This creates a low resistance electrical contact point, which provides electrical continuity and secure connection. A21421207 terminal blocks are available in a variety of sizes, allowing them to be used in various applications. This type of barrier block also provides the highest level of safety for users. The insulated covers of the blocks provide additional protection from electric shock, while the mounting feet help them grip the surface securely and offer the highest level of stability.A21421207 terminal blocks offer quick and easy installation, as no special tools are required. They can be installed with a screwdriver, making them ideal for industrial applications as well as DIY projects. This barrier block can also be reused and reconfigured, making it a cost-effective solution for many different applications.Overall, A21421207 is an effective barrier block which provides high performance and reliability. This terminal block is suitable for a wide range of applications including panel wiring, automation, electrical systems and signal routing. It offers quick and easy installation, and its strong contact blades and screw ensure a secure connection. A21421207 also provides the highest level of safety and stability, making it a sought after terminal block amongst DIY enthusiasts as well as industrial professionals.
