Voltage rating selection
Ambient temperature
Cable protection
BS88 fuses comply with IEC 60269 standards. They are tested under a voltage at least 10% higher than the fuse rated voltage.
Above an ambient of 40C a general de-rating of 0.5% of the fuse-link rated current per excess degree centigrade is recommended.
gG fuses protect cables against both overload and short circuit. The cable is protected when the following conditions are fulfilled.
Capacitor circuit protection
Transformer protection
Motor circuit protection
Protection against electrical shock
The fuse selection must take into account:-the inrush current occurring when the capacitor is switched on-the harmonic currents during the normal operation of the network-capacitor tolerances
The fuse link should be chosen with a current rating greater than 1.7 times the rated capacitor current. Correction for 0ambient temperature higher than 40 C must be added.
Fuses must be fitted both in the primary and the secondary of the transformer. the fuse selection must take into account the high transient inrush current in the primary of the transformer. Consequently the normal current rating of 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 transformer N
0secondary current when the temperature does not exceed 40 C.
the motor starters manufacturer generally recommend the fuse link rating to be used in conjunction with the motor starter. type 2 co-ordination is easily obtained with mersen fuses in view of having the prearcing 12t values closer to the lower limit of the specified limits of the standard. the gM fuse selection as for an aM fuse requires the melt current at 5s is 7 times the fuse rating
the rule is to disconnect within a time specified by local standards. Generally wiring regulations require a disconnecting time not exceeding 5 seconds for a distribution circuit. it will be less than 1 second in many other cases. The maximum value of each fault loop impedance (Z ) for gG fuse link to BS**: part 2 & 6 are as showns
