概　　述 general

電感性電路的開/關(guān)會引起過電壓，尤其是斷開接觸器線圈時，導(dǎo)致釋放出存儲在磁流電路中的電磁能量，會產(chǎn)生過電壓波和極高的振幅：高達(dá)幾千伏，嚴(yán)重干擾了電子設(shè)備，甚至燒壞了某些敏感性的部件和接觸器觸點(diǎn)。本產(chǎn)品與接觸器線圈并聯(lián)連接可以迅速有效降低斬波，抑制與其相關(guān)的高頻率，保護(hù)電子設(shè)備和接觸器觸點(diǎn)。

　　the operation of inductive circuit causes over-voltages ,in particular on opening of the contactor coil. the electromagneticenergy stored in the coil during contactor closing is restored onopening in the form of surges, the voltage wave and amplitude ofwhich may rise to several kilovolts. the electronic e isseriously interfered, and even some sensitive components andcontact point of contactor is broken.ptc suppressor connects withthe contactor coil with parallel connection, which can andeffectively reduced over-voltage wave,control relativeuency ,protect the electronic e and contact point ofcontactor.
