Product Overview
1. ARXM3 series moulded case circuit breakers include thermal magnetic type, electronic type and leakage type circuit breakers, they have reinforced BMC base, BMC middle cover and nylon upper cover.
2. ARXM3 highlights
The circuit breaker has overload, short circuit and undervoltage protection functions, and can protect lines and power equipment from damage.
1. According to the rated ultimate short-circuit breaking capacity, the circuit breakers are classified into four types: C (economic type), L (standard type), M (medium breaking type) and H (high breaking type).
2. ARXM3E accessories are modularized, safe and reliable, with small volume, high breaking capacity, short flashover, high vibration resistance, etc.
3. The circuit breaker has passed the test requirements of GB/T2423.10 and GB/T2423.18, and can withstand the influence of humid air, salt mist, oil mist and mold
4. The neutral pole type of ARXM3-125~630 is A/B circuit breaker when it is of 4 poles specification, which can have a unique function of "overload alarm without tripping" to ensure the continuity of power supply and meet the requirements of Article 6.3.6 of GB50054.
5. It is required to withstand mechanical vibration with frequency of 2Hz~13.2Hz, displacement of ± 1mm, frequency of 13.2Hz~100Hz and acceleration of ± 0.7g;
3. Material advantages of ARM3 products
One of the material advantages of ARXM3 products ---- heat shrinkable insulating materials
The nylon materials such as the upper cover of ARXM3 are halogen-free VO flame retardant, high and low temperature resistant, aging resistant high-quality plastics, brand: reinforced flame retardant nylon PA66.
The products have longer electrical life and strength, better appearance and higher breaking capacity.
Engineering plastics are resistant to high and low temperatures, ultraviolet rays, aging resistance, good insulation strength, and good dimensional stability of parts to ensure that the product does not degrade performance in complex working environments;
The second material advantage of ARXM3 product---- alloy contact with high silver content: the silver content can reach 95%
1,High silver content, high conductivity, thermal conductivity, arc resistance, electric wear resistance,
2,Preparation of dynamic and static contact material standards and reliable process guarantee, improving the electrical life of circuit breaker by 50%.
The third material advantage of ARXM3 product ---- mechanism:
High quality high carbon steel materials, iron base materials of main iron parts (cold rolled steel 10 # steel) , all adopt A+ materials.
High quality low carbon cold rolled steel is used, and after QPQ salt bath composite treatment, the wear resistance, corrosion resistance and fatigue resistance of metal surface are greatly improved, and the strength, mechanical life and electrical life of parts are improved by more than 10%.
Surface treatment and processing technology of mechanism parts: QPQ heat treatment technology imported from Germany.
1. We selected the operating mechanism (steel) of AceReare Electric and another brand sample to compare the experimental results
The operating mechanism of AceReare Electric has a hardness of 366.1, while the hardness of the other brand is only 252.6, which cannot even reach our lowest value.
The mechanical life and electrical life are very important indicators in the national standard of the circuit breaker, and our circuit breaker operating mechanism needs to reach a certain strength and hardness, so that the circuit breaker will not damage the service life of the circuit breaker in the opening and closing process, while the hardness of the other brand is far lower than the national standard.
2. Carburizing test
Surface treatment process, it tests dense compound layer which enhances smoke and abrasion resistance.
Obvious compound layer was detected from the sample of AceReare Electric, while the other brand showed no data.
The fourth material advantage of ARXM3 products - thermosetting insulating materials
The unique formula material is adopted, which has high strength, good arc resistance, strong insulation, high temperature resistance and good flame retardancy.
The fifth material advantage of ARXM3 product ---- high sensitivity temperature sensor
High quality bimetallic element materials are used, and there is no need to reduce the capacity from -5ºC to 55ºC.
The sixth material advantage of ARXM3 products ---- spring materials with longer temperature resistance and fatigue resistance (50% longer than ordinary springs)
4. Product structure of ARXM3 thermomagnetic circuit breaker
Safety, it can directly disassemble the upper cover of ARXM3 to install internal accessories.
Accessory installation features: humanized design, making installation and replacement more convenient for on-site installation.
5. Usage scenarios of ARXM3 moulded case circuit breaker

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.
