Q 1.How about your experience?

A.We have our own professional factory and R&D department & more than 10 years producing experience

Q 2. What's your advantage ? 

A. We have complete set of machines such as ,injection molding machines and punchers,

with these,we can make by ourselves from the inside parts to outside.

It greatly increases the efficiency and saves the cost.

Q 3. How's the delivery time ? 

A. usually it will take about 15-30 days for production

Q 4. Tell me the standard of package? 

A. For inner box and master carton are made as per international standards,

and we can make special design for you if need.

Also if necessary, will be packed in pallet to avoid any damage.

Q 5.Will be any warranty for your item ? 

A. We offer one year warranty for our products. Please feel assured.

Q 6.Do you accept OEM business ? 

We accept OEM authorization.



Q: The key structure of the contactor
Vacuum contactor: Vacuum contactor is the contact system using vacuum degaussing chamber contactor.
Q: Computer-centric development trend
Compared with the traditional oscilloscope detection, the contact arc arc voltage waveform is accurate
Q: What is the traditional AC contactor contact that does not vibrate?
And permanent magnet AC contactor suction, completely rely on permanent magnet force to achieve, once completed the pull, the voltage fluctuations will not affect the permanent magnetism
Q: What is the difference between the contactor and the relay?
How to distinguish? The difference is that Look at their specific use.
Q: Can the AC contactor cut off the short circuit current?
A separate AC contactor is not actively shut off the short circuit current.
Q: What are the principles of selection of contactors?
When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load
Q: Briefly describe the type of contactor
the permanent magnetism and the spring force act together. In the process of stable operation, the permanent magnet suction is used instead of the previous electromagnetic attraction to keep the armature and the core.
Q: How do I distinguish between contactors and circuit breakers?
Installation methods are fixed, drawer and so on. According to the size of the current and the level of the working voltage can be divided into a variety
Q: How many AC contactors are there?
the main Contact mechanical connection of the auxiliary normally closed contact open, auxiliary normally open contact closed, thus turning on the power
Q: Contactor mainly by the drive system, contact system, arc and other components.
The main contact function is to connect and break the main circuit, control the larger current
