Fuses are circuit protection devices used to intercept an unexpected surge in current or excessive heat, limit its effects, and protect the equipment from damage. A 0034.3880 fuse is a type of fuse that offers overload and short circuit protection in the industrial and commercial electronic equipment.

Application Fields

The 0034.3880 fuse is ideal for supporting the broad range of electrical applications found in industrial, commercial, residential, and automotive settings. Typical application instances include pumps, appliances, lighting, HVAC/apartment heating systems, compressors, welders, and other industrial motor systems.

The 0034.3880 fuse is also commonly found in commercial and consumer electronics. Oftentimes, these fuses are installed in speakers, consumer electronics, and various lighting such as LED lighting systems. Since these fuses are also UL recognized, they can be integrated into components that conform to such standards as the National Electric Code.

An additional application is the use in main breaker protected service entrance transformers, actuators, solenoids — and components used for the control and protection of generator sets.

Working Principle

The 0034.3880 fuse has a melting alloy element, which means it adopts the principle of melting wire or alloycore to prevent overcurrent from passing through. The inner core is made of an alloy with a certain conductivity. The outer housing is made up of a plastic shell and a base, which supports and insulates the thermosensitive element.

If a short-circuit or overload occurs, the excess current that flows through the fuse creates a large amount of heat that melts the alloy core, permanently breaking the circuit and protecting the other components from damage. This effectively cuts power supply and the equipment simultaneously stops. After the fault is cleared up, the fuse needs to be replaced.

The 0034.3880 fuse can be found in several amperage ratings ranging from 1 to 30 amperes, and most have a voltage rating of 600 volts AC or 250 volts DC. They are intended for the use in UL Class H, K, R, and T circuits.

The 0034.3880 fuse provides data centers, industrial manufacturers, technology companies, and other organizations with a reliable and cost-effective way to protect their equipment and products from potential damage.
