Terminal Blocks - Barrier Blocks

T38548-22-0 application field and working principle

Terminal blocks make electrical connections in a secure and reliable manner. They are primarily used for connecting wires, cables and other components within a wide range of electronic circuits. The T38548-22-0 terminal block belongs to a category of terminal blocks known as ‘barrier blocks’, which feature a metal mat-like plate with several poles or vertical portions. As the name suggests, the barrier blocks provide physical barriers between the poles which help to insulate the wires connected to the poles from each other.

Each pole usually has separate screw terminals on the top of the block and below it. The top terminals can be used for connecting the incoming lines while the lower terminals are typically used to connect the outgoing wires. The number of poles can vary from one to several hundred, depending on the application of the terminal block. The barriers ensure that each wire is secure and prevents any short-circuiting or loose connections.

The T38548-22-0 terminal block has eight poles with double-screw clamp terminals on each pole. It is mainly used for connecting high power wires, due to its wide range of efficient wire cross sections (from 0.25 mm^2 to 35 mm^2). It also has separate marking fields, which allow easy identification of each wire. The lightweight design of this block reduces troubles during the installation phase, and the high voltage turns off the switch when a circuit is opened, obviating the need for any additional insulation.

The terminal block is also designed to be fixed on a DIN-rail in an electrical panel. It has a special type of retaining clip, which provides a secure conductor/wire connection. The block is constructed with high-grade copper plated terminals and features an insulation thickness suitable for use in high voltage circuits.

The principle of operation of the T38548-22-0 terminal block is that of a clamping connection. This is achieved by using two screws in each terminal, one at the top and one at the bottom of the block. The two screws act in conjunction to compress the wires they are connected with, thus creating an electrical connection. This connection could be permanent, depending on the application.

In summary, the T38548-22-0 terminal block is a very versatile and effective device used to make secure electrical connections in a wide range of industrial and domestic applications. It is a reliable and safe solution to give a secure and permanent connection to high power wires. With its wide range of features, this terminal block effectively eliminates any potential danger of short-circuiting or loose connections.
