Terminal blocks and barrier blocks are two distinct types of electrical components used to connect and disconnect wires in an electrical system. The CT-11 terminal block is a type of barrier block that is used in a variety of applications and is typically manufactured from heat-resistant materials. This article will discuss the application fields and working principles of the CT-11 terminal block.

The CT-11 terminal block is designed for a diverse range of applications with varying current requirements. For applications with higher current requirements, the CT-11 terminal block can provide an overload protection of up to 240A. This type of terminal block is also used in low voltage applications, industrial control systems, and automation and monitoring systems, and can be used in environments with temperatures ranging from -40° to 85°C. The CT-11 also features a robust construction that is resistant to vibration, shock, and corrosion, making it suitable for use in challenging and harsh environments.

The design of the CT-11 terminal block features a modular construction and a two-level spring bridge that can easily be removed for maintenance. The two-level spring bridge consists of two copper bars that are connected between the barrier block and the connecting components. These connecting components are made of a durable material that resists corrosion and fatigue and is designed to handle frequent and repetitive connection and disconnection of wires. The bridge is also designed to be pressure-resistant and is able to withstand up to 4 times the maximum rated current. This ensures a reliable connection even under extreme conditions.

The working principle of the CT-11 terminal block is based on the principle of electrical switching. A vibrating contact system is implemented, which uses a two-level spring bridge with a flat spring to vibrate between the two adjacent terminals to create or break an electrical connection. The movement of the spring creates an electric arc, which is then used to pass or break the current. This system is designed to ensure that the connection is secure and will not be interrupted if the voltage or current changes.

The CT-11 terminal block is ideal for a variety of applications due to its robust construction and vibrating contact system. This type of barrier block can provide an overload protection of up to 240A and is suitable for use in a wide range of temperatures. The two-level spring bridge ensures a reliable connection under all conditions, making the CT-11 terminal block a versatile and reliable choice for a variety of different electrical applications.
