Terminal Blocks - Barrier Blocks is a common type of connector solutions. This type widely used in electrical and electronics, notably in the use of devices in both industrial and commercial settings. The 1515-ST series is a specific brand of Terminal Blocks and Barrier Blocks designed by TE Connectivity, one of the leading suppliers of industrial connectors. This series has a variety of environmentally-friendly features and exceptional performance. In this article, we will explore the Application Field and Working Principle of 1515-ST series.

Application Field and Types

The 1515-ST series is an excellent all-around solution for industrial and commercial users. TE Connectivity offers a wide range of terminated products, ready for connection in all types of environments. This includes a range of right angle, straight through and pigtail terminations, including solid or flexible insulated wire, with options for taps and surge protections. The options for mechanical termination make this a great solution for environmental locations. This can be beneficial in hazardous, explosive, or extreme temperature locations. The high temperature options offer performance down to 0°C, allowing users to reduce maintenance and replacement costs.

Working Principle

The design of the 1515-ST series includes a spring loaded back-shell and a metal strain-relief for mechanical robustness. The terminal block has a unique design that helps to protect the connections from dust and dirt, as well as prevent any water ingress. Built-in surge protection prevents excessive power or even damage to the circuits. The protection is provided by two integral thermally-sealed diodes that provide a low-voltage current flow. The double thermally-sealed design allows for current-carrying capacity and a long service life, reducing maintenance and replacement costs. This series also features a specialized insulation system to improve heat dissipation and reduce the risk of electrical arc.

In order to meet the demands of varying system complexities, the 1515-ST series features several connection points. They range from single-wire pinch lugs to soldered loop end terminals. All terminals on the 1515-ST have a lock-in feature which helps protect the assembly from vibration or shock. It also allows for an improved strain relief and increased durability. All connections are crimp-abled or screw-type terminals for easy assembly and connection.

The 1515-ST series is designed to meet or exceed the requirements of industry standards, including UL 94V-0 and CSA. TE Connectivity offers a range of temperature ranges for this series, meeting the needs of various environmental conditions. The 1515-ST also delivers consistent quality and reliable performance with a 10-year warranty.

Conclusion

The 1515-ST series offers a complete solution for all types of circuitry and connectivity. It is designed to be versatile, durable, and cost-effective. To deliver reliable performance, it has a range of connection points and types. Its surge protection and integrated insulation systems ensures that connections are safe under extreme conditions. For users in hazardous locations, the high temperature option is a great choice. With its 10-year warranty, the 1515-ST series is an all-around, reliable option for industrial and commercial users.
