The RL250 resettable fuse plug-in series produced by Ruilongyuan Electronics is an over-current protection device, which is processed by a special process by using high-temperature organic polymer under high pressure and high temperature conditions, doped with conductive particles. It has an automatic recovery function: it presents a high-resistance state when over-current occurs, and can recover from the high-resistance state to normal after the over-current subsides, voltage range: 250V, can withstand 0.02-2.0A surge energy.
