7.4.4.36 Pset_ElectricalDeviceCommon

7.4.4.36.1 Semantic definition

A collection of properties that are commonly used by electrical device types.

7.4.4.36.2 Applicable entities

7.4.4.36.3 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.

NominalFrequencyRange IfcPropertyBoundedValue IfcFrequencyMeasure

The upper and lower limits of frequency for which the operation of the device is certified.

PowerFactor IfcPropertySingleValue IfcNormalisedRatioMeasure

Power factor; usually as ratio.

The ratio between the rated electrical power and the product of the rated current and rated voltage

ConductorFunction IfcPropertyEnumeratedValue PEnum_ConductorFunctionEnum

Indicates function of the conductors to which the load is connected. Where L1, L2 and L3 represent the phase lines according to IEC 60446 notation (sometimes phase lines may be referenced by color [Red, Blue, Yellow] or by number [1, 2, 3] etc). Protective Earth is sometimes also known as CPC or common protective conductor. Note that for an electrical device, a set of line conductor functions may be applied.

NumberOfPoles IfcPropertySingleValue IfcCountMeasure

Number of poles that the object would affect.

The number of live lines that is intended to be handled by the device.

HasProtectiveEarth IfcPropertySingleValue IfcBoolean

Indicates whether the object has a protective earth connection (=TRUE) or not (= FALSE).

InsulationStandardClass IfcPropertyEnumeratedValue PEnum_InsulationStandardClass

Insulation standard classes provides basic protection information against electric shock. Defines levels of insulation required in terms of constructional requirements (creepage and clearance distances) and electrical requirements (compliance with electric strength tests). Basic insulation is considered to be shorted under single fault conditions. The actual values required depend on the working voltage to which the insulation is subjected, as well as other factors. Also indicates whether the electrical device has a protective earth connection.

IP_Code IfcPropertySingleValue IfcLabel

IP Code, the International Protection Marking, IEC 60529), classifies and rates the degree of protection provided against intrusion.

IK_Code IfcPropertySingleValue IfcLabel

IK Code according to IEC 62262 (2002) is a numeric classification for the degree of protection provided by enclosures for electrical equipment against external mechanical impacts.

NOTE In earlier labeling, the third numeral (1..) had been occasionally added to the closely related IP Code on ingress protection, to indicate the level of impact protection.

EarthingStyle IfcPropertySingleValue IfcLabel

Indicates the earthing style of the electric device.

HeatDissipation IfcPropertySingleValue IfcPowerMeasure

Indicates the heat dissipation of the electric device measured in power.

Power IfcPropertyBoundedValue IfcPowerMeasure

The actual power and operable range.

NominalPowerConsumption IfcPropertySingleValue IfcPowerMeasure

Nominal total power consumption.

NumberOfPowerSupplyPorts IfcPropertyTableValue IfcInteger/IfcLabel

Indicates the number of power supply ports of the electric device.
