The 250V series resettable fuse is designed to handle high-voltage circuits up to 250Vrms/Vdc. It is an innovative overcurrent protection solution to ensure the safe operation of various high-voltage applications.
This PTC (positive temperature coefficient) device can respond quickly when the current is abnormal, and limit the current by sharply increasing its own resistance, thereby effectively protecting sensitive components from overload or short-circuit damage. Its significant advantage lies in the automatic recovery function: once the fault is eliminated, it can automatically return to a low-resistance state without manual replacement, greatly reducing maintenance costs and downtime.
With its excellent high-voltage tolerance and self-resetting characteristics, the 250V series is an ideal solution for industrial power supplies, telecommunications equipment, smart home systems, LED drivers and other high-voltage DC/AC applications that seek long-term stability and maintenance-free.
