7.11.12.2 Object Description

FuseIdentificationType provides the information regarding the type of the fuse (e.g. part number).

CurrentRated provides the current carrying capacity of a fuse. The unit shall be ampere [A].

VoltageRated provides the maximum open circuit voltage in which a fuse can be used, yet safely interrupt an overcurrent. The unit shall be volt [V].

FuseElementSpeedMarking provides the marking of the corresponding speed of a fuse. The values of the MultiStateValueDiscreteType variable are defined in Table 148 and shall be used. The values 0-199 are reserved for future extensions of this specification. The values 200-299 shall be used for vendor-specific extensions of this variable.
