Terminal Blocks - Barrier Blocks: CT-22 Application Field and Working Principle

Terminal blocks are electrical connectors that serve as a bridge between two individual conductive objects. Generally, they’re used to prevent a direct connection between two sources and are essential for larger and more complex electrical systems. Within the broader category of terminal blocks, one subcategory stands out: barrier blocks.Barrier blocks come in a variety of shapes and sizes, but one type of block is particularly popular: the CT-22. This version’s name comes from its two-pole (2P) configuration and its 2 electrical poles can often be found in a variety of settings. The CT-22 is most popular in industries like aviation, robotics, and instrumentation, and is widely used in power distribution systems and low and medium voltage automation locations.The working principle behind barrier blocks like the CT-22 is fairly simple. In short, they provide a protective layer between two connected or disconnected sections of an electrical circuit. This layer provides electrical insulation and helps to reduce the risk of electrical shocks, short circuits, and other potential hazards. The two poles of the barrier block enable the user to segregate different circuits within a system for a variety of reasons, with the two poles having either a normally closed (NC) or normally open (NO) configuration.When a user sets up the barrier block, the two poles are connected by strips of metal that are insulated from each other. One terminal is connected to the source, while the other is connected to the destination. When both poles are activated, the metal strips are pulled out and a connection is established. The metal strips get pushed back together when the circuit is activated and electricity flows across them, making a connection between the two poles.The CT-22 is suitable for several different applications and is particularly useful in high-voltage applications. It can also be used in a variety of other situations, such as controlling motors, relays, and other electrical devices. Industrial settings, domestic installations, and safety applications are some of the most common uses of barrier blocks.The CT-22 is an example of a compact and versatile barrier block. It’s small size makes it perfect for tight spaces and it’s high-voltage capabilities make it ideal for powering up electrical circuits. The two poles are also designed to be easily connected or disconnected, allowing users to quickly reconfigure their electrical systems as needed. It’s used in a variety of industrial, domestic, and safety applications and is essential for larger and more complex electrical systems.
