Envirinment of use
1,The surrounding air temperature is -5°C to +40°C and the average value of 24h does not exceed +35°C.
2,The altitude of the installation site does not exceed 2000m.
3,The relative humidity of the air does not exceed 50% at a maximum temperature of +40°C; a higher relative humidity is possible at lower temperatures, with the average monthly minimum temperature of the wettest month not exceeding +25°C and the average monthly maximum relative humidity of that month not exceeding 90%, taking into account condensation occurring on the product surface due to temperature changes.
Product Overview
W1 series intelligent universal circuit breakers (hereinafter referred to as circuit breakers) are used in distribution networks with AC 50Hz, rated voltage up to 660V (690V) and below, rated current 200A-6300A, to distribute power and protect lines and power supply equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection function and precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outage. At the same time, it has open communication interface and can carry out "four remote" to meet the requirements of control center and automation system.

1.Q: Are you trading company or manufacturer ?
A: We are manufacturer and specializing in manufacturing good quality of MCCB.
2.Q: How long is your delivery time?
A: Normally 5-10 days if there are goods in stock. Or it will take 15-20 days. For customized items, the delivery time depends.
3.Q: What is your terms of payment ?
A: 30% T/T in advance ,and the balance before shipment.
4.Q : Can you make customized products or packing?
A: Yes.We can offer customized products and packing ways can be made according to customer's requirement.5.Q: Can you offer mould making services?
A: We have made many mould for different customers for years.Wecan offer DMC Thermosetting Compressionmoulding,Thermoplastic injection moulding,Metal stamping moulding.
6.Q: How about the guarantee period?
A: It varies according the different kinds of product. We can negotiate it before place an order.
7.Q: What is your production capacity?
A: We can produce 3000 sets per month.
8.Q: How about the scale of your factory?
A: Our total area is 7000 square meter. We have 300staffs, .40 engineers.9.Q: What tests do you have to confirm the quality of the arc chamber?
A: We have a incoming inspection for the raw material and process inspection for the rivet and stamping. There is also final statistical audit which consisting the measurement of sizes, tensile test and coat examine.
10.Q: What are the countries you have exported to?A: We have not worked directly with foreign customers before, we provide ODM and OEM services for brands in China and then they take our products and sell them to foreign customers, basically to Europe and the Middle East.11,Q: Your products are really good, but we have seen the same circuit breakers on the market nearby and their prices are much cheaper than yours.A: First of all, I would like to emphasise that the price is definitely proportional to the quality. If you are a buyer, you must know that the materials and treatment processes used in our products are better than those of our peers, and the quality is recognised in the same industry. Our factory has a thermosetting workshop, thermoplastic workshop, welding workshop, hardware stamping workshop and assembly workshop, and the rate of self-made parts is as high as 80%. We have also built a new factory in Wuhu to guarantee the supply of parts for us, so that the parameters and various technical indicators such as mechanical life, Icu, Ics, etc. are very stable, and the match between parts is very high, and the service life of the finished product is also very long, which is They can be used in high-end industrial areas and hospitals, where the quality of the circuit breakers is very high. We also have our own technology patents and a very professional R&D team of 30-40 engineers to respond to the various needs of our customers, the development cycle of new products only takes 30-40 days, in the process, unconditionally provide you with technical expenses, we can greatly reduce the cost of communication and research and development costs. if particularly urgent, I can apply to my superiors to set up a customer line for you, specifically for you to assemble MCCB.
