Arm5 Series Double-Break Molded Case Circuit Breakers MCCB 3poles 630AMP

Product DescriptionProduct Overview    ARM5 series plastic case circuit breaker (hereinafter referred to as circuit breaker) is the latest new product developed by our company. Its design reflects the latest current limiting principle and manufacturing technology, and has the characteristics of small and compact, modular, high breaking, zero flying arc, green and environmental protection. The circuit breaker is suitable for connecting, breaking and carrying rated current in circuits with dry AC 50Hz/60Hz, rated insulation voltage of 1000V, maximum rated working voltage of 690V, rated current of 32A-630A, and can provide reliable protection for lines and power-using equipment in case of overload, short circuit and under-voltage. It can also be used as infrequent starting and overload, short-circuit and under-voltage protection for motors. The circuit breaker can be installed vertically (i.e., vertical installation), horizontally (i.e., horizontal installation), and also down into the line. The circuit breaker has an isolation function and its corresponding symbol: "".Product ParametersBasic Info.ModelInm (A)Rated current (In)Type of usePolesUeIcuIcsUeIcuIcsUiUimpMechanical EnduranceElectricalsafelifFlashover distance(mm)ARM5-630L630A400A,500A,630AA Class3P400V/415V85KA85KA550V/690V35KA35KA1000V12KV700010000ARM5-630L630A400A,500A,630AA Class4P400V/415V85KA85KA550V/690V35KA35KA1000V12KV700010000ARM5-630M630A400A,500A,630AA Class3P400V/415V150KA150KA550V/690V50KA50KA1000V12KV700010000ARM5-630M630A400A,500A,630AA Class4P400V/415V150KA150KA550V/690V50KA50KA1000V12KV700010000ARM5-630H630A400A,500A,630AA Class3P400V/415V200KA200KA550V/690V65KA65KA1000V12KV700010000ARM5-630H630A400A,500A,630AA Class4P400V/415V200KA200KA550V/690V65KA65KA1000V12KV700010000 ModelRated current (In)PolesStructure sizeDimensions(W*L*H1 )Dimensions(W*L*H2 )ARM5-630L400A,500A,630A3P140*255*169140*255*110ARM5-630L400A,500A,630A4P185*255*169185*255*110ARM5-630M400A,500A,630A3P140*255*169140*255*110ARM5-630M400A,500A,630A4P185*255*169185*255*110ARM5-630H400A,500A,630A3P140*255*169140*255*110ARM5-630H400A,500A,630A4P185*255*169185*255*110 Main functions and featuresPneumatic protection deviceIn case of short circuit and large current in the circuit, the gas in the contact unit box will be rapidly pressurized, and the pneumatic protection device will quickly pull the operating mechanism to lock under strong air pressure, greatly reducing the damage of short circuit current to other electrical components and buses.Magnetic blowout design: the current flows through the fixed contact to generate an electromagnetic source, which forms an annular magnetic field with the iron core. The arc quickly enters the arc extinguishing chamber under the action of the magnetic field, which is conducive to quickly break the current. The reasonable structure design of moving and fixed contacts makes the short circuit peak value and energy I²t in the protection circuit of this series of products far less than the expected value. Working principle: the current flows in from the fixed contact    1, flows out from the fixed contact    2 through the moving and fixed silver contact and the moving contact. The moving contact quickly disconnects under the action of strong electric repulsion force (Holm force and Lorentz force) to improve the breaking speed.Air blowing design: when short circuit and large current occur in the circuit, gas producing parts produce gas under the high temperature of the arc, the air pressure in the contact unit box increases rapidly, and high-speed air flow can be formed through the air outlet of the arc extinguishing chamber, which can effectively extinguish the arc. Packaging & 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)ARM5-630-330050125.5*140*123.5 Cardboard boxe428*19.5*1841.8cm*38.4cm*31cm5800  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.
