Dam3-160 Moulded Case Circuit Breaker Compact Size MCCB

OverviewThe rated insulation voltage of the DAM3-160 molded case circuit breaker is 1000V. These circuit breakers are suitable for power distribution circuits with an alternating current of 50-60Hz, a rated operating voltage up to 400V, and rated operating current from 25A to 160A. The circuit breaker is important in distributing power and protecting the circuit and power equipment from overloading, short circuits, and undervoltage failure damage. 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 with the DAM1 series, the DAM3 series have the characteristics of smaller volume, higher breaking capacity, and more energy saving.Electrical parameters of DAM3-160 molded case circuit breakerRated current of frame size Inm [A] 160Rated current [A]25-160Number of poles 2/ 3 / 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]ABCN(AC)50-60HZ 220/230V [KA]18283650(AC)50-60HZ 400/415V [KA]12162536(AC)50-60HZ 690V [KA]46812(DC)250V-2 Poles in series12162230(DC)500V-2 Poles in series681012(DC)750V-4 Poles in series10151822(DC)1000V-4 Poles in series8121518Rated service short-circuit breaking capacity, Ics [KA]    (AC)50-60HZ 220/230V [% Icu]60%60%60%50%(AC)50-60HZ 400/415V [% Icu]60%60%60%50%(AC)50-60HZ 690V [% Icu]60%60%60%50%category of utilization (EN 60947-2)AIsolation conditionBitmapReference standardIEC/EN 60947-2/GB 14048.2Interchangeability-VersionsFixedBitmapPlug-inBitmapDraw-out-Physical parameters of DAM3-160 molded case circuit breaker EnduranceTotal cycles10000Electrical endurance1500Mechanical endurance8500Basic dimensjons-fixed version3/4 Poies W[mm]27(1P) / 54(2P) / 76 / 1013/4 Poies H[mm]5962.5H1[mm]78.5823/4 Poies L[mm]120IntroductionThe DAM3-160 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
