Fuses are an important part of an electrical system, protecting against overloading or short circuits. They are designed to open and break an electric circuit when the current passing through it is too great. The 70R-15/100A is an example of a specialized fuse, developed to serve a specific purpose. This article will explain the application field and working principle of the 70R-15/100A.

The 70R-15/100A is a thermal fuse, meaning that it operates by detecting overheating in the system, rather than by responding directly to the magnitude of the current. It is designed to open and break the circuit when the temperature of the element it is connected to rises above a certain level. This is done through a component inside the fuse that melts at a given temperature, breaking the connection and thus protecting the system.

The 70R-15/100A is designed for use on DC power systems with a maximum voltage of 15 volts and maximum current of 100 Amps. It is commonly used on batteries, which are vulnerable to overcharging and short circuits, or on high-powered systems to protect against catastrophic failure in the event of an overheat.

The working principle of the 70R-15/100A is simple. It consists of a conductive element, such as a wire, that is connected to a thermal sensor inside the fuse. This sensor is set to detect temperatures above a predetermined level. When this threshold is passed, the sensor will cause the conductive element to melt, breaking the circuit.

The 70R-15/100A is designed to be both reliable and cost-effective. It is made from corrosion-resistant materials and can withstand temperatures up to 200°C. It is also relatively easy to install and maintain. Since the fuse is used in a variety of applications, it is important to make sure that it is matched to the proper current rating and voltage of the system.

In conclusion, the 70R-15/100A is a speciality fuse designed for use on DC power systems. It works by detecting temperature increases, and then breaking the circuit if the temperature rises above a certain level. It is both reliable and cost-effective, and is easy to install and maintain. It should be matched with the proper voltage and current rating for the system it is being used on.
