Terminal Blocks - Barrier Blocks: 2018-ST Application Field and Working Principle

Terminal blocks – barrier blocks have been developed to simplify wiring and installation processes in numerous instances. In particular, the 2018-ST series has been developed to meet stringent safety regulations in environments such as hazardous locations, automation system, and consumer applications. In the following sections, we will discuss the application field and working principle of 2018-ST series barrier blocks.

Application Field

The 2018-ST series barrier blocks are used in a wide range of applications, from hazardous locations to consumer applications.One of the key applications of the 2018-ST series barrier blocks is in hazardous locations, such as petrochemical, process chemical, and mining industries. In these environments, safety is of utmost importance. The 2018-ST series barrier blocks are designed to provide an extra level of protection against arc faults and unintentional connections. Specifically, they are designed to provide high levels of insulation, dielectric strength, and corrosion resistance.In automation systems, the 2018-ST series barrier blocks are used to simplify wiring processes. These blocks provide a secure electrical connection, and the pluggable design minimizes the time required for installation and wiring. This makes it ideal for applications requiring frequent wiring changes, such as for production lines or machine tools.Finally, the 2018-ST series barrier blocks are used in consumer applications. In particular, they are used in consumer electronics such as computers, home entertainment systems, and audio systems. These devices require safe, secure wiring connections, and the 2018-ST series provides that capacity.

Working Principle

The 2018-ST series barrier blocks work by creating an insulated barrier between two conductive surfaces. The block itself is made from an insulated material, usually a high-quality polymer or plastic. The bottom of the block has three metal strips that provide the electrical connection. The metal strips are typically made from copper, brass, or nickel-plated copper.When the barrier block is connected, one of the strips is connected to the source, usually a power source such as a wall outlet or generator. The second strip is connected to the destination, which is typically a consumer device or automation system. The third metal strip is grounded, and is typically connected to an earth ground or a safety ground.When the strips are connected, electricity flows from the source to the destination. The insulated material of the barrier block serves as an isolator between the two, preventing potentially dangerous currents from flowing between them. This not only protects users from shock, but also prevents accidental short circuits.In addition to serving as an insulator, the barrier block also protects against dust and other foreign objects. Dust and other debris can easily accumulate on unprotected metal surfaces, which can cause short circuits and other problems. The barrier block keeps these issues to a minimum, providing a safe and reliable wiring connection.

Conclusion

The 2018-ST series terminal blocks – barrier blocks offer a safe and reliable wiring solution for a wide variety of applications. They provide an insulated barrier between two conductive surfaces, and the pluggable design makes them easy to use. These blocks are used in harsh commercial environments, automation systems, and consumer applications. In all these applications, the insulated barrier blocks offer safe and reliable wiring connections for all electrical needs.
