Specializing in the production of
Use a clamp-on ammeter to measure the current, then observe the thermal relay action current, if it is indeed larger than the action current, please check the motor, if the motor is not a problem, replace the high-capacity thermal relay, such as than the thermal relay action current is small, need to replace the thermal relay.
As AC contactors can be switched on and off frequently in the course of their work, it is inevitable that there will be wear and tear on the contactors in the course of their use.
This kind of device has overload protection function, mainly used for In asynchronous motors, it is very critical. Moreover, this device is very advantageous because of its small size, simple structure and low price. After installation, it is necessary to pay attention to adjusting it, so how to adjust the thermal overload relay?
Classified by production process: copper wire lugs (copper tube stamping and forming), copper-aluminum composite copper wire lugs (suitable for copper-aluminum double conductors).
Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in electric power, power distribution and power consumption occasions. In a broad sense, contactors refer to the use of coils flowing through currents in industrial electricity to generate magnetic fields, so that The contact is closed to control the load of the electrical appliance. Next, let's take a look at the classification method of AC contactors and some related knowledge.
The copper terminal can be subdivided into 34 specific different models. This type of copper terminal is made of high-quality copper and has high conductivity. You can choose the specific type according to the cross-sectional area of the connectable wire. Models, wires and areas from 1.5 square millimeters to 50 square millimeters can be connected using this terminal block.
