Littelfuse 8 A Resettable Fuse, 16V Radial Lead PolySwitch RGEF Series RGEF800

The Littelfuse RGEF800 8 A Resettable Fuse is a PolySwitch™ device from the RGEF series designed for PCB wire ended radial lead applications. It operates at 16 volts and features a hold current of 8 amperes, with a trip current of 13.6 amperes activating within 5 seconds to protect circuits from overcurrent situations.

This resettable fuse automatically switches rapidly from a low resistance state to a high resistance state upon detecting an electrical overload or short circuit. It quickly and automatically resets once the fault condition is corrected and power is restored, providing reliable maintenance-free circuit protection.

Measuring 12.7 mm in length, 20.9 mm in height, and 3 mm in width, with power dissipation rating of 3 watts, it is suitable for compact electronic designs. The fuse maintains performance across a broad temperature range from -40°C up to 60°C, making it robust for various industrial and commercial applications.

Certified by UL, CSA, TUV, and RoHS standards, this fuse guarantees quality and regulatory compliance, ensuring safe integration into electrical and electronic systems.

The device is widely used in security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers and peripherals, as well as audio, visual, and telecommunications equipment.

Automatically resets itself thousands of times without maintenance. Compact size eliminates the need for a fuse holder. Radial lead orientation for easy PCB wiring. Power dissipation of 3W supports safe continuous operation.

Operates reliably across temperatures from -40°C to 60°C. Hold current of 8A with fast trip response at 13.6A. Low electrical resistance for efficient protection. Meets major international safety and environmental standards.

Suitable for industrial, laboratory, automotive, and telecommunications use cases.
