Uchungechunge lwe-HR17B uhlobo lwe-fuseisinqamulelingokusebenza komthwalo, ofanele i-40A ~ 1600A yamanje elinganiselwe, kukhona iqembu eli-1, amaqembu ama-2, amaqembu ama-3, amaqembu ama-4 wamaphuzu. Ingafakwa kubha yebhasi , ingabuye ifakwe epuleti elilungisiwe; inikeza okokufaka okungaphezulu nangaphansi kanye nesakhiwo sokuphumayo, ngesingeniso sommese kanye nedivayisi yokulawula i-arc; futhi ikhava ye-switch inezimbobo zokutholwa ezivaliwe ezingajwayelekile, iswishi yesignali eyakhelwe ngaphakathi, iswishi yokuthola. kungaba i-fuse monitor yokuzikhethela, ingasetshenziswa futhi njengokushintsha kommese. Iswishi enomumo omuhle, inoveli nokufinyezwa, ihlangabezana namazinga e-IEC60947-3, GB14048.3.
