OSOO4.5Z Application Field and Working Principle

OSOO4.5Z fuse is designed for protection of moderately large currents in electric, electronic and communication systems. It is made up of a metal strip, a fuse element, an end cap and a carrier. The carrier acts as a holder for the different components and provides electrical insulation between the end cap and the fuse element. It also acts as a heat sink, regulating the heating effect of the fuse element when under operation.

The fuse element is made from a special alloy, and contains expansion liquid which vaporizes in the presence of heat, causing the fuse to open. When the load current exceeds the rating of the fuse, the alloy and expansion liquid starts to vaporize. This heat vaporizes the metal strip, causing it to expand and break the electrical circuit. Once the overload is stopped, the fuse element cools down and the metal strip contracts to its original shape, forming the electrical connection and resetting the fuse.

The application field of the OSOO4.5Z fuse includes motor protection, capacitor protection, inductive load protection, uninterruptible power supply systems, lighting systems, heating systems, and electronic equipment protection. It provides direct over-current protection for the connected equipment and can also be used as protective fail-safe device. It can be fitted to a variety of electric transmission and distribution boards to provide fast and effective protection.

The OSOO4.5Z fuse offers excellent protection to the connected equipment, with a very quick-acting response time. It is a highly reliable protective device due to its ability to open the circuit in a matter of milliseconds and to readily reset after an overload has been cleared. The fuse is extremely convenient for use as it does not require any specialized installation tools or techniques for installation or replacement.

The OSOO4.5Z fuse is designed for prevention of excessive current and voltage fluctuations in electric, electronic and communication systems. It is a cost-effective protective device, providing fast and dependable over-current and short-circuit protection to ensure the safety and reliability of the connected equipment.
