PTC Resettable Fuses are becoming increasingly more popular with application in many different fields due to their ability to reset themselves after a fault current has been detected and then cleared. The CL20 7R0120 is a particularly popular model of Fuse and is commonly used in industrial and residential applications in order to protect against short circuits and excessive currents in a wide variety of situations.

The working principle of the CL20 7R0120 PTC Fuses is based upon the principle of self-resetting after detecting a certain amount of current. This can be explained by the example of a simple circuit with a source, a switch, a fuse, and a short circuit. When the circuit is operated and the switch is closed, the current will start to flow through the circuit and the fuse. When the current reaches the rated value of the fuse, it will trigger the fuse to open, thus disconnecting the circuit and preventing the short circuit from damaging the equipment or devices by causing a current spike and overloading them.

Once the initial current spike is removed, the PTC Fuse can reset itself once again and therefore allow the same circuit to operate without being damaged. This makes the PTC Fuse ideal for both industrial and residential applications as it can provide a reliable and safe way to protect both circuits and equipment from any potential damages due to short circuits.

The CL20 7R0120 PTC Fuse also offers the advantage of being able to be used in a wide range of operating temperatures, from -20°C up to +85°C as well as being able to withstand a maximum of 5 Amp of current. This makes it suitable for a wide range of applications, both indoors and outdoors. Furthermore, the CL20 7R0120 PTC Fuse is very easy to install and has a very small size and low profile, making installation quick and efficient.

In conclusion, the CL20 7R0120 PTC Fuse is particularly suitable for many different applications due to its strong current protection capabilities, its wide temperature range, as well as its simple installation. Furthermore, the ability of this PTC Fuse to reset itself after detecting a fault current and thus allowing the same circuit to operate again without any damages makes it an attractive option for a wide range of applications in industrial and residential environments.
