RT1-20/125V/150V series

RT1-20 (E) with TUV certification, size 5 x 20±0.5, ceramic tube, time-lag, high breaking fuses can be used with holders or clips.

In the process of circuit-breaking of the fuse, because of the circuit voltage, the arc will occur in the gap when melting off, fuse with high quality should avoid as much as possible this arc, and can withstand the circuit voltage added to both ends after it breaks the circuit.

Fuse as a safety element must have two basic functions of electrical performance and security at the same time. Because the quartz sand has a strong cooling effect on the arc, the arc is quickly extinguished, and during the whole process of breaking current, the silent light, high breaking capacity, good security.
