Product Overview
ARM1E series electronic plastic case circuit breakers (hereinafter referred to as circuit breakers) are suitable for infrequent switching and infrequent starting of motors in circuits with AC 50HZ, rated insulation voltage of 1000V, rated working voltage of 400V and rated working current of 1250A.
The circuit breaker has overload long-delay inverse time limit, short-circuit short-delay inverse time limit, short-circuit short-delay fixed time limit, short-circuit instantaneous and undervoltage protection functions as well as residual current protection (optional) phase failure protection function (optional), which can protect the line and power supply equipment from damage, the circuit breaker has complete and precise protection characteristics, which can improve the reliability of power supply and avoid unnecessary power outages, of which "Z, B "type control with communication interface, can be "four remote" to meet the requirements of the control center and automation system.
According to its rated limit short-circuit breaking capacity, the circuit breaker is divided into L type (standard type), M type (higher breaking type) and H type (high breaking type). The circuit breaker has the characteristics of small size, high breaking capacity, short flying arc and vibration resistance.
The circuit breaker can be installed vertically (i.e., vertical installation), or horizontally (i.e., horizontal installation), and can be installed lying flat.
Circuit breaker with isolation function, the corresponding symbol: "The circuit breaker can not be inverted into the line, that is, only allow 1, 3, 5 connected to the power line 2, 4, 6 connected to the load line.
Envirinment of use
1,The surrounding air temperature state is: -5ºC~+40ºC
2,The altitude of the installation site does not exceed 2000m
3,The relative humidity of the air at the installation site does not exceed 50% at the highest temperature of +40ºC, and can have a higher relative humidity at lower temperatures, such as up to 90% at 20ºC. Special measures should be taken for the occasional condensation due to temperature changes.
4,The pollution level is 3
5, wet and hot band type (TH type) circuit breakers through GB/T2423.4, GB/T2423.18 test requirements, can withstand the effects of humid air, salt spray, oil mist, mold.
6,The circuit breaker should be installed in a place where there is no danger of explosion and no conductive dust, not enough to corrode the metal and destroy the insulation
7, the circuit breaker should be installed in a place where there is no rain or snow intrusion
8,Operating conditions: the circuit breaker passes the test requirements of GB/T 2423.1 and GB/T2423.2, the surrounding air temperature can be as low as -25ºC (ARM1DC/ARM3DC/ARM6DC can provide temperature as low as -40ºC, consult our company), as high as +70ºC (more than 40ºC reduced capacity use, see the technical information in the attached sample)

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.
