PTC Resettable Fuses are safety protection devices that combine both overcurrent protection and self-resetting capabilities. The MF-USMD035-2 is a type of resettable fuse that is commonly used for circuit protection in a wide variety of applications. In this article, we will look at the application field and working principle of the MF-USMD035-2.
Application Field
The MF-USMD035-2 is a two-pole resettable fuse with a rated current of 35A and a rated voltage of 14V. It is mainly used in automotive circuits, AC/DC application, as well as low voltage primary protection. The MF-USMD035-2 can be used in series for higher power ratings or in parallel to increase the current handling capability. Other application fields include uninterruptible power supplies, photovoltaic systems, and protection of electronic circuits used in home audio and video systems.
Working Principle
The MF-USMD035-2 is a self-reset fuse that utilizes a thermal cut-off element. The thermal cut-off element consists of two thin metal strips that are separated by an insulating material. When the current exceeds the rated current of the fuse, the thermal cut-off element heats up and expands, disrupting the electrical path and causing the current to be cut off.
The thermal cut-off element slowly cools down after the current has reached a safe level and the electrical path is restored, allowing the fuse to reset itself. This resetting capability of the MF-USMD035-2 makes it suitable for protecting active electronic devices from overcurrent conditions while not having to be replaced after each overcurrent event.
Conclusion
The MF-USMD035-2 is a two-pole resettable fuse that is commonly used for circuit protection in a wide range of applications. Its application fields include automotive circuits, AC/DC application, photovoltaic systems, and protection of electronic circuits used in home audio and video systems. Its thermal cut-off element allows it to reset itself after an overcurrent event, making it suitable for protecting active electronic devices.
