Terminal blocks are a type of electrical connection and disconnection system, typically used in a wide array of industries and applications. The A-TB381-TT20 is a terminal block widely used in industrial applications, and is part of a larger series of terminal blocks. In this article, we will explore the application fields and working principle of the A-TB381-TT20 terminal block.
What Is the A-TB381-TT20?
The A-TB381-TT20 is a 0.2-6mm² cable-entry screw terminal block. It supports both solid and stranded cables, and is widely used in industrial applications. The terminal block has screw-clamp terminals and is stackable, making it ideal for tight spaces. It has a mounting height of 6.5mm and is IP67-rated, meaning it is dust-tight and protected against water ingress from any direction.
Application Fields
The A-TB381-TT20 is used in a variety of industrial applications, such as:
- Automotive
- Robotics
- HVAC
- Railways
- Marine & offshore
- Aerospace & Defence
The terminal blocks\' small size, IP67 rating, and ability to handle high electrical currents makes it suitable for use in a variety of different industries and applications. It is also easy to install and highly reliable.
Working Principle
The working principle of the A-TB381-TT20 is very simple. It uses a screw-clamp terminal to secure the wire in place. The wire is inserted into the terminal block and secured using the screw-clamp terminal, which is tightened to secure the connection. Once the connection is secure, electricity can then flow between the two terminals.
The terminal block is also stackable, allowing two or more terminal blocks to be connected together using a plate or other means. This allows for multiple connections to be made in a very small space, making it ideal for use in tight spaces. It also helps to reduce the number of splices that need to be made in order to make the connection.
Conclusion
The A-TB381-TT20 is a widely-used terminal block in industrial applications. It is small, easy to install, and highly reliable. It is IP67-rated and capable of handling high electrical currents, making it suitable for use in a variety of industries and applications. Its working principle is simple, using a screw-clamp terminal to secure the connection in place.
