TRK6-4U-380/60-G 關(guān)于AC220V單相供電系統(tǒng)，剩余電流互感器只要套住L/N兩根電源線即可，但要求中性線N此后不容許再接地。對于AC380V三相供電系統(tǒng)，由于有三相三線制、三相四線制、三相五線制等使用狀況，則根據(jù)具體情況將剩余電流互感器同時套住A/B/C三相電源線，或同時套住A/B/C/N線。同理，要求中性線N此后不許再接地，保護線PE不得穿過互感器。
TRK6-4U-380/60-G在系統(tǒng)接地的形式為TN-C型時工業(yè)自動化網(wǎng)，必須將其改造為TN-S型、TN-C-S型或局部TT型系統(tǒng)后，才可以安裝剩余電流檢測裝置。
(2)關(guān)于溫度
TRK6-4U-380/60-G溫度測量與系統(tǒng)接地的形式無關(guān)，主要考慮包括線纜在內(nèi)的低壓配電裝置中關(guān)鍵部位的溫度，一般在二級保護的線路中應用。溫度探頭Pt100可采用接觸式布置法，當被檢測對象為絕緣體時，宜將探測器的溫度傳感器直接設置在被探測對象的表面。當被檢測對象為配電柜內(nèi)部溫度變化時，可采用非接觸式布置，靠近發(fā)熱部件。
5.2 系統(tǒng)設計中的點位分配
根據(jù)國家標準GB13955-2005《剩余電流動作保護裝置安裝和運行》4.4條中關(guān)于分級保護的規(guī)定，安裝剩余電流火災監(jiān)控裝置時，點位分配原則的步驟是：
(1)TRK6-4U-380/60-G研究分析被控低壓AC380V/220V配電線路的相關(guān)圖紙，將建筑電氣的分布情況調(diào)查核實，確定配電設備(如配電柜、箱、盤、電纜等重要設備)的位置，把每一個監(jiān)控探測器分配到相應的配電設備上，以此來確定探測器的數(shù)量，避免重設浪費。
(2)確定分級保護。為了縮小發(fā)生人身電擊事故和接地故障切斷電源時引起的停電范圍，通常在供電線路的不同地點安裝三級(或兩級)不同容量的剩余電流保護裝置，以形成分級保護。根據(jù)用電負載及線路情況，一般分兩級或三級保護，適用于城鎮(zhèn)和農(nóng)村第一級和第二級保護。
其中，重要線路應包括安防、消防、應急電源、通道照明線路及不容許停電的重要場所。
(3)TRK6-4U-380/60-G二級保護中，所有開關(guān)處都要設置安裝剩余電流火災監(jiān)控探測器，即在線路的電源端(第一級保護)和分支首端(第二級也稱為末端保護)都要安裝剩余電流探測器，并接入電氣火災監(jiān)控系統(tǒng)，只作火災監(jiān)控報警用。
(4)TRK6-4U-380/60-G溫度檢測是以配電設備異常時發(fā)熱為基本原則而進行的。
