7.4.4.64 Pset_ProtectiveDeviceTypeFuseDisconnector

7.4.4.64.1 Semantic definition

A coherent set of attributes representing the breaking capacity of a fuse, defined in accordance with IEC 60269. Note - A protective device may be associated with different instances of this pSet providing information related to different basic characteristics.

7.4.4.64.2 Applicable entities

7.4.4.64.3 Properties

Name Property Type Data Type Description
FuseDisconnectorType IfcPropertyEnumeratedValue PEnum_FuseDisconnectorType

A list of the available types of fuse disconnector from which that required may be selected where:

EngineProtectionDevice: A fuse whose characteristic is specifically designed for the protection of a motor or generator. FuseSwitchDisconnector: A switch disconnector in which a fuse link or a fuse carrier with fuse link forms the moving contact, HRC: A standard fuse (High Rupturing Capacity) OverloadProtectionDevice: A device that disconnects the supply when the operating conditions in an electrically undamaged circuit causes an overcurrent, SemiconductorFuse: A fuse whose characteristic is specifically designed for the protection of sem-conductor devices. SwitchDisconnectorFuse: A switch disconnector in which one or more poles have a fuse in series in a composite unit.

VoltageLevel IfcPropertyEnumeratedValue PEnum_VoltageLevels

The voltage levels for which the data of the instance is valid. More than one value may be selected in the enumeration.

IC60269 IfcPropertySingleValue IfcElectricCurrentMeasure

The breaking capacity in [A] for fuses in accordance with the IEC 60269 series.

PowerLoss IfcPropertySingleValue IfcPowerMeasure

The power loss in [W].

The power loss in [W] of the fuse when the nominal current is flowing through the fuse.

NumberOfPhases IfcPropertySingleValue IfcCountMeasure

Number of phases that the equipment operates on.

ReferenceEnvironmentTemperature IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Ideal temperature range.

BreakingCapacity IfcPropertySingleValue IfcElectricCurrentMeasure

The current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.

ArcExtinctionType IfcPropertySingleValue IfcLabel

Type of arc extinction used.

NumberOfPoles IfcPropertySingleValue IfcCountMeasure

Number of poles that the object would affect.

Number of poles that the equipment would affect.

TransformationRatio IfcPropertySingleValue IfcRatioMeasure

The ratio of the actual primary current or voltage to the actual secondary current or voltage.

NominalFrequency IfcPropertySingleValue IfcFrequencyMeasure

The nominal frequency of the supply.

NominalCurrent IfcPropertySingleValue IfcElectricCurrentMeasure

The nominal current that is designed to be measured.

RatedVoltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum.
