7.8.4.39.3 Properties
Name | Property Type | Data Type | Description | |
---|---|---|---|---|
RatedCurrent | IfcPropertyBoundedValue | IfcElectricCurrentMeasure |
The current that a device is designed to handle. |
|
RatedVoltage | IfcPropertyBoundedValue | IfcElectricVoltageMeasure |
The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum. |
|
InsulationVoltage | IfcPropertySingleValue | IfcElectricVoltageMeasure |
The insulation voltage. The max voltage for normal insulation operation. |
