用途 Purpose-
  CZT-30直流电磁接触器具有超级开关能力和高电器寿命,直流电压高达1000V,电流达30A,Ith为50A。环境温度范围-40℃--+70℃。该接触器主要用于电力机车、内燃机车、电动车组辅助电路和控制电路中接通和分断电路。
     该接触器的磁系统为螺管直动式,主触头为一具有自净功能的桥式双断点,其上方装有引弧片和两排灭弧栅片,两边配有一对永久磁钢,当分断触头产生电弧时,利用永久磁钢将电弧吹向引弧片再进入灭弧栅片,从而快速熄灭电弧。辅助触头为一只微动开关即具有3个接线端子的单断点转换型式(也可并装两微动开关),当电磁线圈通电衔铁动作时,带动微动开关切换。
     该产品既可导轨安装也可螺钉紧固。

     CZT-30 DC Electromagnetism Contactor has super switch capability and high electrical life. Its DC Voltage can be high at 1000V. Circuit is 30A.Ith is 50A. Ambient temperature range is -40 +70. This contactor is mainly used in junction and disjunction circuit of electric-power engines, internal-combustion engines, electro-motion vehicles assistant and dominate circuit.
     The magnet system of this contactor is whorl-pipe straight motion mode.Main contact is a two-point bridge brake with self-clean function. Above it, it is fixed leading are slice and two row extinguished are slice bar. Both sides furnish a pair of permanent magnetism steels. When the disjunction contact generates electric are, it can blow the electromagnetism to leading are slice to extinguish the electric are quickly. Assistant contact is a jiggle switch. This switch is a single disjunction transfer mode which has 3 connection sides(Also can install two jiggle switch). When the electromagnetism coil has a motion through electromagnetism iron, it can draw the jiggle switch to open or cutthe circuits.
  This product can also be fixed by rail or tighten bolt.
