MCCB Dam3-400 3p 400A CB Approved Moulded Case Circuit Breaker

OverviewThe rated current of the Dada DAM3-400 molded case circuit breaker can reach up to 400A. 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 1600A. 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 DAM3-400 molded case circuit breakerRated current of frame size Inm [A] 400Rated current [A]200-400Number 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]CNSH(AC)50-60HZ 220/230V[KA]455580105(AC)50-60HZ 400/415V [KA]30365570(AC)50-60HZ 690V [KA]12152025(DC)250V-2 Poles in series30355065(DC)500V-2 Poles in series12182230(DC)750V-4 Poles in series18304255(DC)1000V-4 Poles in series15253545Rated service short-circuit breaking capacity, Ics [KA]    (AC)50-60HZ 220/230V [%Icu]60%60%60%60%(AC)50-60HZ 400/415V[%Icu]60%60%60%60%(AC)50-60HZ 690V [%Icu]60%60%60%60%category of utilisation(EN 60947-2)AIsolation conditionBitmapReference standardIEC/EN 60947-2/GB 14048.2InterchangeabilityBitmapVersionsFixedBitmapPlug-inBitmapDraw-outBitmapPhysical parameters of DAM3-400 molded case circuit breakerEnduranceTotal cycles8000Electrical endurance1000Mechanical endurance7000Basic dimensions-fixed version3/4 Poies W[mm]120/159140/2103/4 Poies H[mm]100100H1[mm]133.51353/4 Poies L[mm]180215IntroductionThe DAM3-400 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.  /* 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
