Dam1-160 1p 16-160A Semko Approved Molded Case Circuit Breaker

IntroductionThe DAM1 series circuit breakers are intended for conducting current in normal mode and switching it off at short circuits, overload, inadmissible bucking as well as operational actuation and tripping of electric circuit parts. They are designed for use in electric units having the operative voltage limited to 400V per rated current from 12,5 to 1600A. They correspond to the requirements of EN 60947-1, EN 60947-2 Thermal-Magnetic Circuit Breakers:Thermal protection function:(For protection under over load conditions) Bimetal,  which provides thermal protection, consists of combination of two metals with different extension coefficients under heat. When bimetal is heated, it bends towards the metal with less extension. In this way, a notch that assists opening of the breaker mechanism is released to disable the breaker. Bending speed of bimetal is in direct proportion with size of the current passing through the breaker. Because, increase of current means increase of heat. In this way, over current protection function of the breaker is fulfilled by bimetal at load currents higher than the rated current Magnetic protection function (For protection under short circuit conditions) Another function of the breaker is to protect the connected circuit against short circuits. Short circuit may occur as a result of contact of phases with each other or contact of phase-ground. Since a very high current shall pass through the cables in case of short circuit, system energy should be broken in a shorter time due to thermal protection. Breaker should perform instant opening to protect load it is connected to. The part fulfilling this function is a mechanical opening mechanism that operates with magnetization caused by the magnetic area formed by the short circuit current.  Thermal-Magnetic fixed type Circuit Breakers ModelDAM1-160Breaking Capacity CodeBNRated Current of Frame size- Inm                                                                    (A)160ARated Current-In(40,50 or 55ºC)                                                                      (A)10 - 12,5 - 16 - 20 - 25 - 32 - 40 - 50 - 63- 80 - 100 - 125-160ARated İnsulation Voltage -Ui(a.c.) 50-60Hz                                                    (V)500VRated operation Voltage  -Ue(a.c.) 50-60Hz                                                    (V)230VNumber of Pole1PRated ultimate short Circuit breaking Capacity  kA  Icu AC400V/50Hz O-CO          (KA)2536Rated service short Circuit breaking Capacity  kA  Ics AC400V/50Hz O-CO-CO     (KA)18.7527Rated short-circuit breaking capacity Icm(peak)/cos ф AC400V/50HZ O-CO         (KA)40/0.3135/0.25Rated impulse withstand Voltage -Uimp                                                                            (V)10000Dielectric Propery (V)2500lonization distance                                                                                                              (mm)≤30/0EnduranceTotal Cycles20000Electrical Life3000Mechanical Life17000Over Current tripThermal and Magnetic release fix type√Category (EN 60947-2/IEC 60947-2)Main circuitA/0Auxiliary circuitAC-15Under Voltage Release -Shunt Release-Auxiliary Contact-Alarm Contact-Auxiliary Contact and Alarm Contact-Handle Operation Mechanism-Electrical Operastion Mechanism -DIN clips√Terminal cover  -Phase seperator  -Extention Handle  - W (mm)1P304P-L (mm)1P1204P-H (mm)1P704P-  /* 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
