What is a Terminal Block - Barrier Block?

Terminal Blocks-Barrier Blocks are electrical components used to connect and disconnect two different electrical circuits. The terminal block is usually used for the connection of single or multiple wires in a circuit. Barrier blocks are designed to provide easier access to the electrical connections as they have a barrier compartment between the terminals which can be opened or closed by lifting up or pushing down the bar. Barrier blocks also provide improved safety as they protect the terminals from dust flooding and accidental contact.

T37157-21-0 Application and Working Principle

The T37157-21-0 Barrier Blocks series is designed to support power supplies, AC/DC switching converters, and relay circuits. The T37157-21-0 has a 3-polar configuration with integrated flexible cable connectors and is designed to interconnect multiple PCBs without the need for soldering. The flexible connectors provide quick installation and a low-profile profile for easy mounting.The T37157-21-0 is also designed for use in a wide range of industrial and home applications. Its rugged design and corrosion-resistant coating make it an ideal choice for harsh environments and equipment used in the medical, electric, defense and transportation industries.The T37157-21-0 has a double-pole design which allows for a single connection point and eliminates the need for multiple connections. The flexible connection makes installation faster and easier while also providing higher currents handling capability and improved electrical insulation.The working principle of the T37157-21-0 is a two-way connection, which is achieved by introducing a barrier between the two connections. The polarity of the connection is determined by the direction of the connection and is liable to create a secure connection between the two cables.The T37157-21-0 has a number of mounting choices and comes with three retention screws, enabling it to be directly mounted onto any flat surface. The screws are used to secure the terminal and provide the necessary rigidity and stability for the connection.

Conclusion

The T37157-21-0 Barrier Blocks series is designed for use in a wide range of industrial and home applications. Its double-pole design, flexible connection and mounting options provide quick installation and high current handling capability. The T37157-21-0 also provides improved safety and corrosion-resistant coating, making it an ideal choice for harsh environments and medical, electric, defense and transportation equipment.
