一、西門子3TF30接觸器應用范圍 
西門子系列交流接觸器用于交流 50Hz 或 60Hz，額定絕緣電壓為690-1000V，
在 AC-3 使用類別下額定工作電壓為 380V 時的額定工作電流為 9A-400A。
主要供遠距離接通及分斷電路之用，適用于控制交流電動機的起動、停止及反轉。符合 IEC947，VDE0660，GB14048等標準
二、西門子3TF30接觸器產品特性

結構特點1 總體結構接觸器為雙斷點觸頭的直動式運動機構，具有三對常開主觸頭，輔助觸頭可有二常開，二常閉。接觸器觸頭支持件與銜鐵采用彈性鎖扣聯(lián)結，消除了薄弱環(huán)節(jié)。動作機構靈活，手動檢查方便，結構設計緊湊，可防止外界物及灰塵落入活動部位，接線端都有防蓋，人手不能直接接觸帶電部位。接觸器外形尺寸小巧，安裝面積小。安裝方式可用導電導軌安裝，也可用螺釘緊固，與其它同類產品相比，操作頻率和控制容量更高。產品安全、可靠性好，為*的接觸器機各種。2觸頭系統(tǒng)主、輔助觸頭材料由電性能*的銀合金組成，具有使用壽命長及良好的接觸可靠性。滅弧室呈封閉型，并有阻燃型材料阻擋電弧向外噴濺，Ie≤22A無滅弧隔弧板。Ie≤22A裝有金屬隔弧板，保證人身及臨近電器的安全。接線螺釘采用新型自升螺釘，瓦形墊與螺釘不分離可節(jié)省接線用時。3磁系統(tǒng)電磁系統(tǒng)工作可靠，損耗小、噪音低、具有很高的機械強度，線圈的接線端裝有電壓規(guī)格的標記牌，標記牌電壓等級涂有特定的顏色，清晰醒目，接線方便，可避免因接錯電壓規(guī)格而導致線圈燒毀。
