Product Description
The Littelfuse RGEF250 Resettable Fuse is an advanced polymer-based poly-switch circuit protection device engineered for automotive, industrial, and electronic applications. Featuring a hold current of 2.5A and trip current of 4.7A, it reliably protects sensitive circuits against excess current and short circuit events.
This fuse is designed to automatically reset thousands of times after fault conditions, returning to its low-resistance state once power is cycled and the overload is removed. Its compact radial-lead profile allows straightforward PCB assembly without the need for an additional fuseholder, optimizing space in control boards, power supplies, and instrument panels.
The fuse supports a maximum voltage of 16V and allows operation across a wide temperature range, from -40°C to 60°C, making it suitable for outdoor and industrial environments. The robust construction and compliance to RoHS, TUV, UL, and CSA standards ensure safe usage and high operational reliability.
Applications include security systems, power supplies and transformers, power switching devices, automotive electronics, medical instruments, instrumentation, computers, peripherals, audio visual equipment, and telecommunications.
The Littelfuse RGEF250 fuse offers maintenance-free resistance switching, rapid protection response, and quick return to service after clearing the fault. Choose Littelfuse fuses for advanced circuit protection and explore the full range of Electrical Fuse solutions in the EnvMart catalog.
