CT-21

Terminal blocks, also known as barrier blocks, are an essential component of any electrical system. They connect wires and cables to devices, making it easier to manage and debug the system.The CT-21 Terminal Blocks, which are widely used in industrial automation systems, are one type of terminal blocks. In this article, we will cover the application field and working principle of CT-21 Terminal Blocks.

Application Field

CT-21 terminal blocks are often used in industrial automation systems to manage and distribute power and provide electrical connections between the various components. They are commonly found in HVAC systems,switchgear systems, automation systems, motion control systems, CNC machine control, robotic systems, and many other applications. They are used to provide a safe and secure connection between two elements of an electrical system.

Working Principle

CT-21 terminal blocks are designed with a screw-clamp terminal. The terminal blocks have two parts that are connected together, a busbar and a flat clamp terminal strip. The flat clamp terminal strip fits into a groove and is secured by a screw. The screw is tightened once the flat clamp terminal strip is in place, creating a secure electrical connection between the two parts. Once connected, the voltage from the busbar is transferred through the flat clamp terminal strip and onto the device in question.

CT-21 terminal blocks are also designed with a seal and insulation component in order to protect against environmental damage and prevent electrical shorts. The seal and insulation provide insulation against rain, wind, and other elements, while also providing a physical barrier to shield against any sparking or arcing that could occur during connection or disconnection of the electrical components.

In order to ensure safety in any industrial automation system, it is important to ensure that all connections are secure and properly insulated.CT-21 terminal blocks provide a reliable connection with a secure seal and insulation to keep the system running safely and properly.
