Above an ambient of 40C a general de-rating of 0.5% of the fuse-link rated current per excess degree centigrade isrecommended. gG fuses protect cables against both overload and short circuit.The cable is protected when the following conditions arefulfilled. Capacitorcircuitprotection Transformerprotection Motorcircuitprotection Protectionagainstelectricalshock Thefuseselectionmusttakeintoaccount: -theinrushcurrentoccurringwhenthecapacitorisswitchedon -theharmoniccurrentsduringthenormaloperationofthenetwork -capacitortolerances The fuse link should be chosen with a current rating greater than 1.7 times the rated capacitor current. Correction for 0 ambienttemperaturehigherthan40 Cmustbeadded. Fuses must be fitted both in the primary and the secondary of the transformer. the fuse selection must take into accountthehightransient inrush currentintheprimaryofthetransformer.Consequently thenormalcurrentratingof the fuse links on the primary side of transformers should be at least twice the nominal transformer primary current. the normal I value of the fuse links on the secondary side of transformers is at least equal to the nominal transformerN 0 secondarycurrentwhenthetemperaturedoesnotexceed40 C. the motor starters manufacturer generally recommend the fuse link rating to be used in conjunction with the motor starter.type2co-ordinationiseasilyobtainedwithmersenfusesinviewofhavingtheprearcing12tvaluesclosertothe lower limit of the specified limits of the standard. the gM fuse selection as for an aM fuse requires the melt current at 5s is7timesthefuserating the rule is to disconnect within a time specified by local standards.
