3211777 application field and working principle

The 3211777 type series terminal block is a positioning and mounting mechanism with multiple screw terminals. It is widely used in different applications fields, such as buildings, electricity engineering, oxygen machines, water treatment and other control systems. It is especially suitable for family distribution box, industrial motor, switch control boxes, DC power modules, junction box lightening protection and other places.

The terminal block of this type consists of a base connected with a connecting part and a terminal unit. The outer surface of the terminal unit is provided with a sealing layer, two nuts, two screws, and a transparent cover. The terminal block includes two contact points, one is insulated and the other connected to the earth wire.

The working principle of 3211777 terminal blocks is that the two nuts on the terminal unit clamp the corresponding terminal screws. The terminal screw makes electrical contact with the clamped contact point by compressing the clamping part. Meanwhile, the support core is connected to the middle layer of the assembly body, creating a stable electrical connection. At the same time, the transparent protective cap can provide effective protection for the circuit.

In summary, 3211777 type terminal block can provide customers with reliable products with a variety of features such as multiple contact points, strong corrosion resistance and smaller contact gap. Compared with other terminal blocks in the industry, it enjoys superior performance, stable electrical connection and easy installation. Besides, the transparent protective cap also provides effective protection for the circuit.
