Littelfuse 1.1 A Resettable Fuse 30V DC Radial PolySwitch RUEF110

Littelfuse RUEF110 is a PolySwitch resettable fuse designed to protect electronic circuits by automatically interrupting excessive currents up to 2.2A at 30V DC. With a hold current of 1.1A, it ensures safety for PCB mounted devices with its radial lead configuration and small form factor of 7.4mm length, 14.2mm height, and 3mm width.

This fuse features a rapid switch from a low resistance state to a very high-resistance state when an electrical overload or short circuit occurs. Upon removal of the fault condition and power, it resets automatically without replacement, allowing thousands of cycles and maintenance-free operation.

Operating temperature ranges from -40°C to 60°C, with a maximum power dissipation of 0.7W, making it reliable for diverse environments. Approved by CSA, RoHS, UL, TUV, and CQC, it meets stringent safety standards required in industrial and commercial applications.

Main applications include circuit protection in security systems, power supplies and transformers, automotive and medical equipment, instrumentation and control systems, computers, peripherals, audio-visual and telecommunications gear.

This Resettable Fuse automatically resets multiple times for prolonged service life. Compact radial lead design facilitates easy PCB mounting. Meets multiple international approvals ensuring quality and reliability. Provides effective protection against electrical overloads and short circuits.

Compatible with wide-ranging industrial and electronic applications. Maintenance-free and small size eliminates the need for fuse holders.
