CT-2 type terminal blocks are a type of barrier blocks that have been used for many years in a wide range of applications. The primary purpose of CT-2 barrier blocks is to reduce the risk of dangerous electric arcs, electrical short circuits, and the possibility of shock to personnel within the working area. This is achieved through the use of barrier blocks between power and auxiliary lines, which are used to physically separate the two sets of wiring.

The CT-2 block consists of a pair of connecting clamping rails, comprised usually of aluminum or copper. A series of spring loaded contacts act as a barrier between the two wires, while a pair of small grooved rail screws securely connect the two rails together and act as a barrier. The contacts are usually made of aheat resistant material, such as nickel-plated steel or brass, and are designed to open and close depending on the electrical connection that needs to be made.

CT-2 terminal blocks can be used in a variety of applications, including distribution boards, motor starter circuits, motor control systems, and medical equipment. In addition to their use as a barrier, CT-2 blocks are also used in connection with various control systems. They provide an easy method for connecting and disconnecting electrical circuits in a safe and efficient manner.

The working principle of a CT-2 terminal block is relatively simple. When power is applied to the block, the contacts close and allow current to flow across them. This creates a connection between the two rails, allowing power to be transferred between them. When the circuit is open, the contacts open again, and the circuit is no longer energized.

CT-2 blocks also offer a number of other features, such as the ability to detect over-voltage, over-current, and temperature rise. This helps to protect the components of the application and ensures that the circuit remains safe. Additionally, CT-2 blocks can also detect the number of contacts in the circuit, which can be used to maintain a constant and safe electrical connection.

In summary, CT-2 type terminal blocks are a type of barrier blocks that have been used for years in many applications. They are designed to reduce the risk of dangerous electric arcs and electric shocks to operators and personnel within the working area. They provide a secure connection between power and auxiliary lines, as well as offer features such as over-voltage detection and temperature rise detection.
