6.35X31.75mm ceramic tube quick-break fuse merchant
Due to the presence of inductance or capacitance in the line, the instantaneous inrush current of the line switch machine often occurs. The inrush current may be 7~10 times of the normal working current. The pulse width and waveform vary with the line, and the inrush current is in the circuit every time. Switching machines will appear, need to use time-delay fuses, according to the degree of anti-surge, there is a medium delay, delay and long delay difference, sometimes in order to protect important components, such as thyristors, ICs, hope a fault current The fuse-link is quickly disconnected, and a fast-fuse or fast-fuse fuse should be selected.
