Product Details
Place of Origin: | Zhejiang, China | Brand Name: | CHANGKAI/SINOAMIGO | Model Number: | ZBM-DB |
Product Description
Features:
1. New generation LED display screen, with a switch signals, energy storage instructions.
2. The function of auto reclosing test, to test the circuit breaker performance.
3. Drive circuit short circuit protection, namely the faulty connection of inner drive circuit in the
circuit breaker, and causing no damage.
4. One of the switching power supply technology, that is combined with the divide shut drive
power supply and working power supply, to reduce the probability of damage. It can stability
output drive voltage of the divid shut brake under the input voltage less than 100V.
5. Used the key component capacitor made in Korea, with high quality 2000h in 105 ℃ , to
ensure the stability product quality.
6. With the large scale of 0.01A~50A accurate sampling, it achieves less to 2% tolerance.
Technical parameter:
The controller is designed according to national industrial standard design, and every index is
consistent with DL/T721-2000 requirement. The detail data as follow below diagram 1:

Our story with customers
In 2005,we received the email from ALIBABA that a Russian customer would like to order the KYN28-12 indoor metal-clad enclosed switcgear.We confirm the product parameters and pictures carefully again and again with the client,the last communication is the most difficult in price,it is a psychological warfare,customers began to demand a 20% cut,we insist on our price,emphasis on the various advantages of our products with the high quality. After compared with other factory,Russia customer finally chose to coperation with our company.After more than 20 days,customers sent a email to tell us that they are very satisified with the goods. At the same time,he praised our good service attitude,delivery on time,good quality,until now the Russia client has been our long-term customer,also is our good friend.
