NH40系列負荷隔離開關
NH40系列負荷隔離開關(以下簡稱開關)是我公司引進歐洲先進技術研制而成，該產品具有國際九十年代末期水平,是國內同類產品中理想的更新換代產品。開關廣泛適用于建筑、電力、石油化工及其它行業的配電系統和自動化系統。
模塊化設計結構，具有靈活多樣的組合性，采用玻璃纖維增強不飽合聚脂樹脂制造外殼，有很高的介電性能，防護能力和可靠的操作**性。操作機構是彈簧蓄能、瞬時釋放的加速機構瞬時接通與分斷雙斷點觸頭結構。與操作手柄的速度無關，極大提高了各項電氣性能與機械性能。
多種結構與操作方式，有直接觀察觸頭通斷狀態的窗口，有柜內、柜外操作，有正面、側面操作，有板后接線。開關造型美觀、新穎、簡潔、體積小功能全，是同類產品中理想的選擇。
產品特點：彈簧蓄能瞬時釋放時加速機構實現了快速接通與分斷（13.8米/秒），與操作手枘速度無關、極大提高了熄滅電弧能力。由玻璃纖維增強不飽和聚脂樹脂制造的外殼具有良好的阻燃性能、介電性能、抗碳化性和抗沖擊性。并聯雙斷點觸頭具有自潔作用。所有觸頭材料是銅鍍銀合金，具有兩個分離觸頭面。隔離距離大。在“0”位時，可同時用三把鎖鎖住手柄，可靠避免誤操作。
產品用途:NH40系列負荷隔離開關主要用于交流50Hz，額定電壓660V，直流額定電壓440V，額定電流至4000A。用于不頻繁接通與分斷電路與線路的隔離之用。
