Terminal Blocks - Accessories – 0920397 Application Field and Working PrincipleTerminal blocks are devices with socket outlets used to connect electrical wiring and are an essential component for any electrical installation. Terminal blocks fall under the category of accessories that includes various mounting accessories such as support systems, bridging bars, and cages like those used for wire organization. The 0920397 terminal blocks are safety components designed to meet IEC/EN standards for safety, insulation, impact protection, reliability and durability. As components of Terminal Blocks - Accessories, they are used in various applications such as control panels, electro-mechanical systems and alarm systems.0920397 terminal blocks are designed based on uniform current carrying rated elements embedded in a metal zinc body up to 4 mm in size. The body is designed to be durable and safe, while the zinc element ensures a low contact resistance. The joint between these two metal parts ensures the mechanical strength of the product. The design makes it easy to connect wires of different sizes up to 4 mm in diameter. In addition, the 0920397 terminal blocks have an insulation sleeve attached to the body. This makes it possible to make connections using insulated cable cores and guarantee electrical insulation of the connections in the terminal blocks.The terminal blocks are connected by using screws to mount it securely to the installation panel or support. Factors such as humidity, temperature, vibration and shock are considered when designing the terminal blocks to prevent the dislodging of screws and wires, as this would result in incorrect wiring. The working environment strongly affects the reliability of the connection to the terminal blocks. An ideal working environment is one that is free from vibrations and shocks, low temperature and humidity, and no flammable gases or materials near the mounting surface.Once properly aligned, the 0920397 terminal blocks make accurate and lasting connections. They provide several advantages compared to other connection methods, such as better contact integrity, low contact resistance due to strong and wear-resistant contacts, easy installation and flexible application. They are suitable for a wide range of applications, such as process control systems, cables, and harnesses.To summarize, 0920397 terminal blocks are devices that have socket elements embedded in a metal zinc body, with proof for safety, insulation, impact protection, reliability and durability that allow for a safe electrical connection. They are used in variable applications due to its flexibility and easy installation.
