ZTH熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)保(bao)護繼電(dian)(dian)(dian)(dian)(dian)器(qi)監控(kong)商(shang)用熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)溫度。可將高(gao)達6個熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)串(chuan)聯連接到(dao)傳(chuan)感器(qi)端(duan)子(zi)P1和(he)P2。繼電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)連接到(dao)端(duan)子(zi)A1和(he)A2（230VAC）或(huo)A3和(he)A2（24V AC/DC）。綠色(se)LED指(zhi)示電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)連接。由于ZTH采用閉路原理(li)，一旦傳(chuan)感器(qi)電(dian)(dian)(dian)(dian)(dian)阻(zu)小于1.5k，輸(shu)出繼電(dian)(dian)(dian)(dian)(dian)器(qi)就會立即切(qie)換到(dao)工作位置。在(zai)熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)達到(dao)其標稱關閉溫度（傳(chuan)感器(qi)電(dian)(dian)(dian)(dian)(dian)阻(zu)> 3.2k）后(hou)，繼電(dian)(dian)(dian)(dian)(dian)器(qi)切(qie)換到(dao)其靜止(zhi)位置。該狀態(tai)(tai)由紅色(se)LED指(zhi)示。測量電(dian)(dian)(dian)(dian)(dian)路與電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)隔離。前面板上的(de)DIP開關用于選擇傳(chuan)感器(qi)的(de)短路監控(kong)和(he)重(zhong)新(xin)啟動抑制(zhi)器(qi)。重(zhong)新(xin)閉合互鎖是零電(dian)(dian)(dian)(dian)(dian)壓保(bao)護。重(zhong)啟禁止(zhi)是零電(dian)(dian)(dian)(dian)(dian)壓保(bao)護。在(zai)電(dian)(dian)(dian)(dian)(dian)壓故障的(de)情況(kuang)下存儲最后(hou)的(de)開關狀態(tai)(tai)由雙穩(wen)態(tai)(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)完成。
