Contactors contact point working principle
Working principle: since it is a point to move, then it is necessary to contactor electricity, whether the contactor, relay, time relay, all need electricity to work.So we will use the contact coil here, you look at the picture, the contactor coil working voltage, we will use the contactor is 22...Read more -
Analysis of mechanical characteristics of vacuum contactor
The performance of vacuum arc extinguishing chamber determines the performance of contactor, and the mechanical characteristics of contactor itself also determine the performance of vacuum arc extinguishing chamber.Whether the performance of a vacuum contactor meets the requirements mainly depend...Read more -
A new energy saving contactor or capacitor special energy saving contactor
AC contactor is widely used in low-voltage circuit, it is a kind of safe use, convenient control, large amount and a wide range of industrial necessities.China is now generally used in 40A and above large and medium capacity of AC contactors should be more than 100 million meters, its operating e...Read more -
How to select MCCB?
Plastic shell circuit breaker (plastic shell air insulated circuit breaker) is widely used in the low-voltage distribution industry, used to cut off or isolate the normal and rated range of fault current, to ensure the safety of lines and equipment.In addition, according to the requirements of Ch...Read more -
How to wire AC contactor? AC contactor wiring skills
Communicate the principle of AC contactors. When the coil is plugged in, the iron core of the static transformer causes the eddy current adsorption force to digest and absorb the iron core of the dynamic transformer. Because the contact point system software is connected with the moving transform...Read more -
AC Contactor cable connection method
Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, distribution and electricity occasions.In a broad sense, contactor refers to industrial electrical appliances that use coil current to generate a magnetic field and close the contacts t...Read more -
How to choose a contactor, factors to be considered when choosing a contactor, and steps for choosing a contactor
1. When selecting a contactor, the following elements are critically considered. ①The AC contactor is used to operate the AC load, and the DC contactor is used for the DC load. ②The stable working current of the main contact point should be greater than or equal to the current of the load power c...Read more -
Thermal overload relay function
Thermal relay is mainly used to overload protect the asynchronous motor. Its working principle is that after the overload current passes through the thermal element, the double metal sheet is bent to push the action mechanism to drive the contact action, so as to disconnect the motor control circ...Read more -
Appearance of plastic shell circuit breaker
There are many types of circuit breaker, usually we contact more of the number of plastic shell circuit breaker, let’s first through a picture to see what the real body of the plastic shell circuit breaker is like: Appearance of plastic shell circuit breaker Although the shape of different ...Read more -
Structural principle of the contactor
Structural principle of the contactor Contactor is under external input signal can automatically turn on or off the main circuit with load automatic control appliances, in addition to control motor, can also be used to control lighting, heating, welder, capacitor load, suitable for frequent opera...Read more -
The three major attributes of the AC contactor
First, the three major attributes of the AC contactor: 1. The AC contactor coil.Cils are usually identified by A1 and A2 and can be simply divided into AC contactors and DC contactors. We often use AC contactors, of which 220 / 380V is the most commonly used: 2. Main contact point of the AC conta...Read more
