Description

мента 4 с нижней токоведущей крышкой 3 и гашение дуги в наполнителе. При больших токах повреждени  отключение электрической цепи проиеходит до момента срабатывани  релейной защиты при сгорапии плавкого элемепта 4.4 with the lower current-carrying lid 3 and arc quenching in the filler. At high currents of damage, the disconnection of the electric circuit occurs until the moment when the relay protection trips when the fusible element 4 is ignited.
