1518-YWY terminal blocks are one of the most popular barrier blocks produced by Phoenix Contact. These blocks are designed for securely connecting electrical and electronic components, with a maximum motor rating of 16A and 250V for the standard blocks or 660V when using insulated barriers. The 1518-YWY is also used for bridging connection of input and output signals on the same line to prevent currents from flowing from one terminal to the other.

These blocks have several features that make them ideal for a wide range of electrical applications. They are available in different types such as pluggable, push-in, and screw mounting options. Additionally, the blocks have a touch-safe design with an integrated system of self-locking optional pins that ensure a secure connection. The housing of the terminal blocks is made of thermoplastic material that provides insulation and protection against dust and dirt. Moreover, the blocks have clamping mechanisms that enable the connection of cables with an insulation diameter of 3 to 5mm.

The working principle of the 1518-YWY barrier blocks is quite simple. The terminals are designed with an insulated barrier and the current flows through the terminals until it reaches the barrier. The barrier acts as a protective shield which prevents current flowing from one terminal to the other. This ensures that the user does not get an electrical shock even when the terminals are touched. The terminals also feature a double locking system which ensures that the wires are firmly connected to the terminals.

The 1518-YWY barrier blocks can be used in a variety of applications including bridge motors, lighting systems, control circuits, and UPS systems. Furthermore, they are suitable for use in hazardous environments, as they feature an intrinsically safe design which prevents electrical shock. The blocks also come with a wide range of accessories such as ground bars, end covers, mounting clamps, rail clips, and marking plates, so you can customize the terminal block according to your specific application.

In conclusion, the 1518-YWY barrier blocks from Phoenix Contact are an excellent choice for securely connecting electrical and electronic components and ensuring their safety. The terminals feature an integrated insulated barrier and a double locking mechanism which help prevent current from flowing between entities and ensure a secure connection. Additionally, these blocks are suitable for use in a variety of applications and can be customized to meet specific requirements.
