Dam3-1600 3p CB Ce Molded Case Circuit Breaker MCCB

Dam3-1600 3p CB CE Molded Case Circuit Breaker MCCBOverviewThe rated current of the Dada DAM3-1600 molded case circuit breaker can reach up to 1600A. These electrical devices are suitable for the protection of power distribution circuits with an alternating current of 50-60Hz and a rated operating current to 1000A. They can also be used in electric motors for infrequent starting and overload protection as well as protection against short circuiting and undervoltage conditions.Compared to the DAM1 series, the DAM3 series are designed for smaller volume, higher breaking capacity, offering better energy savings.Electrical parameters of DAM3-1600 molded case circuit breakerRated current of frame size Inm [A] 1600Rated current [A]1000 1250 1600Number of poles3 / 4Rated operating voltage(AC)50-60HZ [V]400/690DC [V]250/1000Rated impulse withstand voltage Uimp [KV]8Rated insulation voltage Ui[V]750Test voltage at industrial frequency for 1 min [V]3000Rated ultimate short-circuit breaking capacity Icu [KA]SHG(AC)50-60HZ 220/230V [KA]80105130(AC)50-60HZ 400/415V [KA]5570100(AC)50-60HZ 690V[KA]202530(DC)250V-2 Poles in series506580(DC)500V-2 Poles in series223040(DC)750V-4 Poles in series425568(DC)1000V-4 Poles in series354555Rated service short-circuit breaking capacity, Ics [KA]   (AC)50-60HZ 220/230V [%Icu]60%60%60%(AC)50-60HZ 400/415V [%Icu]60%60%60%(AC)50-60HZ 690V[%Icu]60%60%60%Category of utilisation(EN 60947-2)AIsolation conditionBitmapReference standardIEC/EN 60947-2/GB 14048.2InterchangeabilityBitmapVersionsFixedBitmapPlug-inBitmapDraw-outBitmapPhysical parameters of DAM3-1600molded case circuit breakerEnduranceTotal cycles5000Electrical endurance1000Mechanical endurance4000Basic dimensjons-fixed version3/4 Poies W[mm]210/2803/4 Poies H[mm]140H1[mm]1963/4 Poies L[mm]328IntroductionThe DAM3-1600 molded case circuit breaker automatically cuts off the current when the current exceeds the release setting. The molded case refers to the plastic insulator used as the frame of the device to insulate the conductor and the metal grounding component.Working principleThe main contact of the DAM3-1600 molded case circuit breaker is manual manipulation or electric closing. After the main contact is closed, the free release mechanism locks the main contact into the closing position. The overcurrent trip coil and the thermal trip element are connected in series with the main circuit. The undervoltage trip coil and the power supply are connected in parallel.  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
