The Estimation of the Polymer Fuses Features

摘要

The protection of electrical circuits against the overload or short circuits is usually achieved by the single use of blow-out fuses. The paper contains the examining results of the multiple use of polymer fuses. The static and dynamic characteristics of selected fuses are acquired on the test station. Some interesting features of the polymer fuses, not included in datasheets, are carried out. The courses of characteristics in comparison to their technical data with elements of accuracy analysis are discussed.
