Since the over-current protection scheme to restore power circuit fuse: traditional circuit, are generally used to do one-time fuse over-current protection, or select the type of the fuse is too large, the failure can not be timely protection, either too small, also do not protect the fuse will fuse, serious impact on the customer the normal use function. When the circuit fails, the self recovery fuse or fuse, self recovery fuse do over-current protection action, fast response time, as long as the exclusion of the fault circuit, power can automatically restore the state before. To appear in the circuit of pulse current / surge current has certain inhibition ability, so the self recovery fuse or fuse, self recovery fuse current protection application in fuse has unique properties and other incomparable advantages.
Self recovery fuse by polymer and conductive nano particles by a special process, when a failure happens, the current circuit inside the will increase, through the self recovery fuse will be fever, immediately can become high resistance conductive links fracture. To achieve the purpose of protection, as long as the troubleshooting, re energized, you will be able to resume work.
