Introduction To Terminal Block

The unit of the wiring terminal block is "bit", and a wiring position is 1 "bit". Usually the so-called table is the serial number of the terminal, these serial numbers have different definitions in different applications."Section" and "bit" have the same meaning, but they are called differently. "Group" is composed of "sections".

The usual terminals have 2, 3, 4, 6, 12, etc., which are divided by number. According to the capacity: 10A, 20A, 40A, etc.

In the power electronic distribution wiring, when the devices inside the screen are connected with the devices outside the screen, they must pass through some special wiring terminals. The combination of these wiring terminals is called a terminal block. The function of the terminal block is to connect the devices in the screen to the lines of the external devices, and play the role of signal (current and voltage) transmission. With the terminal block, the wiring is beautiful, the maintenance is convenient, the connection between the long-distance wires is mainly reliable, and the construction and maintenance are convenient.

Wiring terminal blocks, commonly used English letters and numbers, or Chinese pinyin letters plus numbers, are used to indicate the current flow at the connection point of the terminal block, as well as the size and number of terminals of the terminal block. It is also used to indicate the manufacturer's series of products. Model.

Commonly used terminals (rows) with a rated voltage of 380V have
