Fuses are fundamental devices that protect electrical circuits, and the 7020.8530 is a particularly reliable type. It is produced in two different models, 7020.8530-11 and 7020.8530-45, with each having its own specific features and applications. Regardless of the model, both are single-pole (3 POLE) thermal fuses with a fast blow-up time, allowing them to work in stringent applications.

Applications

The 7020.8530 is mainly used in power supplies, medical equipment, consumer electronics, lighting, and industrial equipment. It can also be used in harsh environments, such as those with extreme temperatures, where more precise overcurrent protection is needed.

Common applications include protection of power supplies against over-current/over-voltage/over-temperature, motor lead protection, and protection against short circuits. Medical applications such as surgical lamps and medical monitors may also benefit from the use of the 7020.8530.

Working Principle

The 7020.8530 is a highly reliable thermal fuse, working using the principle of thermal release. It consists of one or more thin strips of metal that are heated by an increase in electrical current. When the current reaches a specified amount, the metal strip melts, breaking the circuit and releasing an electric arc. This releases a large amount of heat, melting the metal strips that then open the circuit.

The 7020.8530 is specifically designed to open the circuit quickly in the event of over-current/over-voltage/over-temperature or short circuits. The fast blowing time of the fuse is its most important feature and the reason it is so effective in protecting electric systems. In addition, the 7020.8530 is typically designed with two layers that are thermally fused together, allowing it to open quickly, even if the arc is small.

Overall, the 7020.8530 is a reliable and effective thermal fuse that is suitable for a variety of applications. It is able to quickly detect and open a circuit if an over-current/over-voltage/over-temperature or short circuit occurs, providing the necessary safety protection for electrical systems.
