电感性电路的开/关会引起过电压，尤其是断开接触器线圈时，导致释放出存储在磁流电路中的电磁能量，会产生过电压波和*高的振幅：*几千伏，严重干扰了电子设备，甚至烧坏了某些敏感性的部件和接触器触点。本产品与接触器线圈并联连接可以**降低斩波，抑制与其相关的高频率，保护电子设备和接触器触点。

　　The operation of inductive circuit causes over-voltages , in particular on opening of the contactor coil. The electromagnetic energy stored in the coil during contactor closing is restored on opening in the form of surges, the voltage wave and amplitude of which may rise to several kilovolts. The electronic equipment is seriously interfered, and even some sensitive components and contact point of contactor is broken.PTC suppressor connects with the contactor coil with parallel connection, which can quickly and effectively reduced over-voltage wave,control relative high frequency ,protect the electronic equipment and contact point of contactor.
