1516-ST

Terminal Blocks - Barrier Blocks

1516-ST is a variety of terminal blocks made from heavy-duty PVC and insulated with an overall tinned copper conductor. It is used mainly in applications that need high-current protection and high reliability. Terminal Blocks are used in the construction of electrical systems to permit multiple connections to be made between different parts and components of the system. A barrier block is a type of terminal block with a fence-like barrier surrounding it, thus providing high current protection. The 1516-ST terminal blocks offer users high reliability, strength, and electrical shielding.

Application Field

1516-ST terminal blocks are most often used in industrial, high-current, transformer-based applications such as motor control panels, electrical switchgears, electronic power supply and variable frequency drives. It is also used for direct current applications such as railway applications, direct current drives, power supplies and telecom applications.

Working Principle

The 1516-ST terminal blocks work on the principle of electrical insulation of conductors from their environment. They are designed in such a way that each individual terminal is insulated from other terminals. This helps to reduce the risk of excessive current, arcing, short circuits, and hazardous overvoltages. Each terminal is barriered off from other terminals by a protective enclosure made of PVC, which helps to increase the mechanical strength against shocks and vibration. Moreover, the overall tinned copper conductor helps to reduce the risk of oxidation and corrosion.

Installation and Maintenance

1516-ST terminal blocks are easy to install and maintain. The user needs to simply extract the cables and insert them into the terminals. Maintenance is also easy as the cables can be removed and re-inserted without any complications. Moreover, the terminals are color-coded for easy identification and come with plug-in terminals to ensure reliable connection with cables.

Conclusion

In conclusion, 1516-ST terminal blocks are a reliable and efficient solution for high-current applications. They provide reliable insulation against current, arcing, and short circuits. They also resist shocks and vibration and come with plug-in terminals for easy installation and maintenance. These terminal blocks are suitable for all types of industrial applications and are an ideal choice for high-current operations.
