0225.500H Datasheet/PDFFuses, also known as circuit breakers, refer to devices that are used to protect circuits and electrical equipment from damage caused by over-current or short circuits. The fuse 0325.500H is a type of thermal fuse which senses the temperature increase and opens the circuit without disconnecting the power line. The working principle of this device is defined in this article.
Application Field of 0325.500H
The thermal fuse 0325.500H is highly used in medical devices such as electrosurgical generators, laser systems, infusion pumps, and x-ray machines. It is also suitable for use in the production of various electronic products. Other than that, the fuse can be found in safety circuits for the protection of electric motors, transformers, computers used in smart home systems, and even home appliances.
Working Principle of 0325.500H
The 0325.500H works by triggering its thermal fuse when the surrounding temperature exceeds its maximum limit. This will result in a rapid increase in the internal temperature of the fuse which will cause it to break the circuit and stop the device from working, thus protecting it from overheating damages. The thermal fuse is also designed to reset itself when the temperature returns to normal.
Theoretically, the internal temperature should be equal to the surrounding temperature in order to activate the fuse. However, this is not always the case especially in facilities with limited space and poor ventilation. In such an environment, the internal temperature will start to increase much earlier than the surrounding temperature, due to the high efficiency of heat transfer.
Conclusion
The thermal fuse 0325.500H is a very effective device in protecting circuits and electrical equipment from over-current and short circuits. It is highly used in the industrial and manufacturing sectors as well as in medical devices, home appliances, and smart home systems. The fuse works by triggering its thermal fuse when the surrounding temperature exceeds its maximum limit, causing it to break the circuit and stop the device from working.
