Arm6hu Series Photovoltaic High-Voltage Molded Case Circuit Breakers MCCB 3poles 250AMP

Product DescriptionProduct Overview1,Overview of high-voltage AC circuit breaker     ARM6HU series moulded case circuit breakers are applicable to string photovoltaic power station systems. Their rated working voltage can be up to 1000V, and can be used in 500V and 800V systems.  2,ARM6HU product highlights1. Advanced and safe arc extinguishing system structure design; 2. Zero flashover can be achieved by installing the protective cover. Double insulation:pole to pole connection and complete isolation of main circuit;The products are widely used in the field of new energy. AC MCCB: series inverter application (power station type): PV string is inverted by inverter DC/AC, and the output AC is boosted and connected to the grid after being converged by AC combiner box. AC combiner box and low-voltage side of box substation shall be equipped with AC circuit breaker, with working voltage of AC500V → AC800V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.In order to improve the insulation performance and short-circuit breaking safety of the product, the reinforced insulating base plate and zero flashover cover are specially made 3, Green:We strictly control the raw materials, process processing technology and auxiliary materials of products according to the requirements of EU ROHS 2.0 directive. 4,Safe and reliable: extremely high mechanical life and electrical life. The mechanism components and release are designed and optimized on the M3 structure platform, ensuring the reliability and tripping accuracy. Mechanical life: 10000 times, electrical life: 2000 times 5,ARM6HU small ampere is characterized by high protection accuracy and long service life.The mechanism components and release are designed and optimized on the M3 structure platform, ensuring the reliability and tripping accuracy. Mechanical life: 10000 times, electrical life: 2000 times  3.Usage scenario of ARM6HU new energy high-voltage circuit breaker 4.ARM6DC and ARM6HU patented technology design innovation1.Large opening distance2.Large capacity metal anti-dissociation grid3.Narrow slit pressurized air blowing solution Product ParametersBasic Info.ModelCurrent shell frameRated current(In)PolesUeIcuIcsUeIcuIcsUiUimpMechanical EnduranceElectricalsafelifARM6HU-250250A63A,80A,100A,125A,140A,160A,180A,200A,225A,250A3PAC800V36.523AC1000V12121140V8kV70001000 ModelRated current (In)PolesStructure sizeDimensions(W*L*H1)Dimensions(W*L*H2)ARM6HU-25063A,80A,100A,125A,140A,160A,180A,200A,225A,250A3P113*165*125113*165*105Packaging & ShippingOuter packaging information (dimensions Weight)Model numberMinimumorderquantityProduct size mm(L*W*H)WeightPacking metho(wooden box/carton)Number of boxesInner box size cm(L*W*H)Outer box size cm(L*W*H)Box weight(g)ARM6HU-250-330050165*113*104.6 Cardboard box 30*20.5*17.5 3850  Accessories and AccessoriesFAQ1.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 thermosett
