20H07-660 electrical specialty fuse is a kind of device that is used to protect equipment from severe surge current or short-term overload. It is mainly used in electrical cabinets, photovoltaic system, power distribution and other applications. The 20H07-660 is a glass tube type delay action fuse. These fuses are made of solid metal line and have a cylindrical shape. It has characteristics like high breaking capacity, a spring loaded middle contact for low resistance and a proven delay time. Each fuse element is tested and meets the strictest quality requirements.

The principle of 20H07-660 fuse is based on the Joule heating effect. The Joule heating effect states that when a current passes through a conductor, it will generate heat due to the resistance of the conductor. As the current passes through the conductor, the conductor will get heat up, and thus the temperature in the conductor will increase. As the temperature increases, the resistance will also increase and the current will drop. When the fuse trips, a metal element will melt and the circuit will open to protect the connected equipment.

The application field of 20H07-660 fuse includes power distribution, communication systems, air-conditioning systems, water-pumps, motors and industrial equipment. In addition, it can also be used in photovoltaic systems to protect solar panels, cable lines, and batteries. The 20H07-660 fuse is an ideal choice for over-current protection as it has a high breaking capacity and a short trip time. The breaking capacity is rated up to 20KW and the trip time is rated from 500ms to 0.8s.

The 20H07-660 fuse is reliable and easy to install. It is alsocost-efficient. It is designed in such a way that it eliminates the chances of sparking and arcing giving it a long and reliable life expectancy. It also eliminates the need for a breaker switch, making it even more cost-effective. The 20H07-660 fuse follows IEC/EN standards and is configured to work in high-voltage systems. The fuse also has a high impact resistance and low vibration resistance. It also has an operating temperature of -30℃ to +175℃.

To conclude, the 20H07-660 fuse is an ideal choice for over-current protection and is widely used in power distribution systems, photovoltaic systems, motors and industrial equipment. It follows strict quality requirements and has high breaking capacity and short trip time features. The fuse also has a long life expectancy, is cost-efficient and easy to install. Furthermore, it also meets IEC/EN standards and can work in high voltage systems.
