Introduction 3/2 Siemens ET B1 AO · 2009, Characteristic curves for fuses 3 ¡Overview Rated voltage Un The rated voltage is the designated voltage of the fuse and and is used to determine its test conditions and operational voltage limits. For LV HRC and SITOR fuse links, the rated voltage is always the r.m.s. value of an AC voltage. In the case of NEOZED and DIAZED fuse links, a distinction is made between AC and DC voltage values. Rated current In The rated current of a fuse link is the designated current of the fuse link and is the current up to which it can be continuously loaded under...

Introduction 3/4 Siemens ET B1 AO · 2009, Characteristic curves for fuses 3 Current limitation As well as a failsafe rated breaking capacity, the current-limiting effect of a fuse link is of key importance for the cost effectiveness of a system. In the event of short-circuit breaking by a fuse, the breaking current continues to flow through the network until the fuse link is switched off. However, the breaking current is limited by the system impedance. The simultaneous melting of all the bottlenecks of a fuse element produce a sequence of tiny partial arcs that ensure a fast...
