Automatic Voltage Regulator – AVR-A-OPT-06 l 17
5 PROTECTION FUSE
The fuse is used to limit the input current supply in order to extinguish the current in case of failure, avoiding major
problems. The AVR-A-OPT-06 regulator possesses a rectifier that controls the field voltage of the alternator. For the
maximum field voltage, the supplied current at input “3” is half of the field current, and the maximum current of the fuse
should be a little more than half of the current supplied by the regulator. Listed below are some of the fuse
characteristics:
Recommended manufacturer: LittelFuse
Characteristics: Fast action fuse.
Dimensions: 5x20 mm.
Current/Voltage: 3A/250V for 5A model or 5A/250V for 7A model (Table 4.1).
