LANTRONIX 080-332-000-R 自动化模块备件
•触点-双断银镉氧化物触点耐焊接，提高可靠性。活动触点为楔形，而固定触点具有独特的“折回”设计。在触点打开时，这种“折回”设计会产生强大的磁场，从而快速将电弧从触点表面抛下。然后电弧被电弧室表面冷却并熄灭。•线圈-接触器线圈采用热固性环氧树脂热压成型，以防止机械损坏和有害环境。线圈分流板设计用于延迟磁通量，直到施加的电压达到“拾取”电压。每个线圈都配有一个专用的热断路器，设计用于在电流过大或电压不当时打开。•磁铁-高效磁铁具有永久气隙。磁极表面磨损不会影响气隙，也不会因残余磁性而导致磁粘。每个磁体叠片都涂有磷酸盐涂层，以提供足够的耐腐蚀性。目录编号说明位置1 234 1370–D C 56 a bc D a产品代码类型1370 DC组件b类型代码描述D不可逆w/DB C设备代码描述C DC回路接触器D额定电流代码安培56 56 110 180 280 280 4罗克韦尔自动化出版物1370-TD001C-EN-P-2013年12月DC回路接触器，接触器凸耳和动态制动器1370直流回路接触器规格接触器额定值触点额定值-常开。
• Contacts - The double break silver cadmium oxide contacts are weld resistant for improved reliability. Movable contacts are wedge shaped, while the stationary contacts have a unique “fold back” design. On contact opening, this “fold back” design generates a strong magnetic field which quickly throws the arc off the contact surface. The arc is then cooled and extinguished by the surface of the arc chamber. • Coil - The contactor coils are hot pressure molded in thermoset epoxy to protect against mechanical damage and harmful environments. The coil shunt plate is designed to retard the magnetic flux until the voltage applied reaches the “pick up” voltage. Each coil is provided with an exclusive thermal cutout which is designed to open on excessive currents or misapplied voltages. • Magnet - The high efficiency magnet has a permanent air gap. Pole face wear cannot affect the air gap and cause magnetic sticking due to residual magnetism. Each magnet lamination is phosphate coated to provide ample resistance to corrosion.
