直(zhi)流(liu)(liu)接觸(chu)器由于(yu)鐵(tie)心(xin)(xin)中(zhong)不會產生(sheng)渦(wo)流(liu)(liu)和磁滯損耗，因此(ci)不會發熱。鐵(tie)心(xin)(xin)和銜鐵(tie)用整塊電工(gong)軟(ruan)鋼做成，為使線(xian)圈散熱良好，通常(chang)將線(xian)圈繞制成高(gao)而(er)薄的(de)圓(yuan)筒狀，且不設線(xian)圈骨架，使線(xian)圈和鐵(tie)心(xin)(xin)直(zhi)接接觸(chu)以利于(yu)散熱。

交流接觸器為了減小因渦流和磁滯損耗(hao)造成(cheng)的能量損失和溫升(sheng)，鐵心和銜(xian)鐵用硅(gui)鋼片疊成(cheng)。線圈繞在骨架上(shang)做成(cheng)扁而厚的形狀，與鐵心隔離，有利于鐵心和線圈的散熱。

永磁溝通交流接觸器是運用磁場的異性相吸、同性相斥的基本原理，用永磁驅動器組織替代傳統式的電磁線圈驅動器組織而產生的一種微功能損耗接觸器。安裝在接觸器連動組織上極性固定不動不會改變的永磁鐵，與干固在接觸器基座上的可變性極性軟磁鐵相互影響，進而做到吸合、維持與釋放出來的目地。軟磁鐵的可變性極性是根據兩者之間干固在一起的電子器件控制模塊造成十幾到二十幾ms的正反面向浪涌電流，進而其造成不一樣的極性。依據當場必須，用操縱電子器件控制模塊來操縱設置的釋放出來工作電壓值，也可延遲時間一段時間再傳出反方向浪涌電流，以做到低壓廷時釋放出來或關閉電源廷時釋放出來的目地，使其操縱的電動機免遭電網晃電而跳停，進而維持生產系統的平穩。傳統式溝通交流接觸器重合閘維持是靠線圈插電使鐵氧體磁芯造成電磁力，使聲響鐵氧體磁芯吸合，當電網工作電壓不夠或聲響鐵氧體磁芯表層不整平或有塵土、臟東西等時，便會有噪聲造成。而永磁溝通交流接觸器重合閘維持是借助永磁力來維持的，因此不容易有噪聲造成。③.無升溫：傳統式接觸器借助線圈插電造成充足的電磁力來維持吸合，線圈是由電阻器和電感器構成的，長期性通以電流量必定會發燙，另一方面，變壓器鐵芯中的磁通量越過也會造成發熱量，這二種發熱量在接觸器腔內一同功效，常使接觸器線圈燒毀，另外，發燙減少主斷路器容積。而永磁溝通交流接觸器是借助永磁力來維持的，沒有保持線圈，當然也就沒有升溫。④.斷路器不振顫：
