Product Name: Factory Hot Sales DC Contactor 250A Magnetic Contactor Type: Dc Contactors Main Circuit Rating Current: 20A Main Circuit Rating Voltage: DC 12V24V48V etc Phase: 1 Number of Pole: Normal Electricity Type: DC Trademark: suntree/oem Transport Package: Carton Specification: CE SAA TUV Origin: Zhejiang Product Description 250A DC contactorThe scope of products:1. it is used for the driving and controlling system of mining equipment and mechanical vehicles.2. it is used for power control and circuit insulation of industrial machinery.3. for DC switch equipment.4. for battery distribution and backup.5. for the charging of hybrid electric vehicles and electric vehiclesThe characteristics of the product:1. reliable sealing makes the product used in bad and explosion-proof environments for a long time, and its coil, contact and other internal components are not oxidized.At the same time, the product has the advantages of low energy consumption, little heating, long life, small volume, lightweight and so on.2. control high voltage and large current3. energy savingSome specifications of the products are used for energy saving.4. smaller arcs are more effective and safer when the product is usedUsing an inert gas seal, the product has no arc between the contacts when the product moves, and the magnetic blow out arc is used. All are guaranteed.5. high stabilityThe internal mechanism and structure are completely sealed in the inert gas and are not disturbed by external factors, and the contact resistance is stable for a long time.6. a wide range of applicationsThe use includes DC power control, battery switch control, circuit safety protection and so on.Coil parametersRated working voltage (Us)9-36VDCWorking voltage range (20ºC)9-36VDCAbsorption voltage (20ºC)8V-9V Release voltage (20ºC)6V-7VCoil power(20ºC)1.7W (Maintain)Coil polarityYesMain contact parametersMaximum continuous overcurrent (External connecting wire cross-sectional area 60mm²min)250AContact Voltage12-900VDCRated control capacity250A 450VDCShort-term tolerance of current350A 900S450A 200SContact Suction Time25ms maxContact release Time10ms maxMaximum split power flow (more than 1 times)2000A 350VContact FormA group of often openContact polarityPolar or infinityContact resistance≤2mΩAuxiliary contact parameterscontact formA group of often openContact resistance15mΩmaxMaximum load2A 30VDC ; 3A 125VACLifeMechanical life2X105secondElectrical life (L/R ≤1ms)6.3X103secondDielectric property parametersContact between points3500V AC/ 60 Sec/1mABetween Contacts and coils2500V AC/ 60 Sec/1mAMechanical propertiesImpact20G Peak, 11ms 1/2 sine wave (coil electrified)Vibration20G Peak, 80~2,000hz, sine waveUsage environmentAmbient temperature-40ºC~+85ºCHumidity5%~85% RH.Altitude<4000mweight: 432gMatters needing attention:1. when installing the contactor, the washer should be used to prevent the screw from loosening.2. the products with the polarity should be connected according to the marking on the end of the product. The position of non-polar products is not required.3. do not install this product in a strong magnetic field (near a transformer or magnet) or close to a thermal radiation source.4. this product has its own electrical life, do not use in excess of its switching capacity and life parameters.5. ensure the use of the environment temperature in the range of -40~+85 C, high temperature is easy to accelerate the diffusion of internal inert gas, avoid storage.Use the product in a high-temperature environment.When 6. resistance load is used, it is used in accordance with the rated parameters of the main contact. If the connection of the inductive load (L load) is L/R > 1ms, this sense should be used.A shunt surges current protection device with a parallel load.When 7. wiring is installed, attention should be paid to ensuring the cleanliness of the main elicited end and connection head and tighten to avoid excessive heating at the lead end connection.FAQQ: How can i trust you and your company ?A: Suntree is a group company, we have 6 subcompanies.
