Product Description

Littelfuse RGEF500 resettable fuse is a high-quality protective device rated for 5 A hold current and 16 V operating voltage, featuring radial lead wires for easy PCB mounting. It offers rapid trip action with an 8.5 A trip current and a quick 2-second trip time to safeguard circuits effectively.

This fuse maintains a low resistance in normal operation and switches to a high resistance state during overload or short circuit, resetting automatically to restore circuit integrity after fault clearance. It provides maintenance-free protection for electrical and electronic circuits and is designed to reset thousands of cycles reliably.

The compact dimensions of 10.4 mm length, 14.3 mm height, and 3 mm width make it suitable for space-constrained applications. It dissipates power up to 2.6 W and operates reliably in temperatures ranging from -40°C to 60°C, meeting stringent safety and quality approvals including CSA, UL, RoHS, and TUV certifications.

This resettable fuse belongs to the PolySwitch™ RUEF & RGEF series and is intended for use in security systems, power supplies, transformers, power switching devices, automotive and medical equipment, instrumentation and control, computers, peripherals, audio visual, and telecommunications equipment.

This fuse resets itself automatically without requiring replacement or maintenance. It provides fast and consistent protection against excessive current conditions. Its compact size reduces the need for fuse holders, aiding design flexibility.

UL, CSA, RoHS, and TUV approvals guarantee compliance and reliability. Suitable across a wide range of industrial and commercial electrical applications. Explore more circuit protection solutions in the Resettable Fuse category at EnvMart for professional-grade electrical equipment.
