Littelfuse 2.5 A Resettable Fuse 30V dc Radial Lead RUEF250

Littelfuse RUEF250 is a 2.5 A Resettable Fuse designed for protecting electrical and electronic circuits against overcurrent conditions at 30V dc. This radial lead fuse features rapid switching from low resistance to high resistance to prevent damage during overload or short circuit events.

The fuse automatically resets thousands of times after the fault condition is cleared, minimizing maintenance and replacement needs. Its small size and radial lead orientation enable easy PCB mounting without requiring a fuse holder.

Key technical specifications include a hold current of 2.5A, trip current of 5A, power dissipation of 1.2W, and trip time of 10.3 seconds. It operates reliably from -40°C to 60°C, ensuring wide environmental tolerance.

This resettable fuse is widely used in security systems, power supplies, transformers, power switching devices, automotive and medical equipment, instrumentation, computer peripherals, audio visual, and telecommunications sectors. It is UL, TUV, RoHS, CQC, and CSA compliant, assuring high safety and quality standards.

Automatically resets itself thousands of times after faults. Maintenance free design requiring no fuse holder. Compact radial lead form factor for PCB wire ended mounting. Rapid transition to high resistance for circuit protection.

Wide application across industrial and commercial electronic devices. Complies with multiple international standards for safety. Operates reliably in temperatures ranging from -40°C to 60°C.

Industrial and laboratory users benefit from the reliable automatic protection this fuse provides. It is an ideal solution for applications requiring repeated fault clearing without fuse replacement.
