Name Property Type Data Type Description
PoleUsage IfcPropertyEnumeratedValue PEnum_PoleUsage

Pole usage.

LongTimeFunction IfcPropertySingleValue IfcBoolean

Applying long time function A flag indicating that the long time function (i.e. the thermal tripping) of the device is used. The value should be set to TRUE for all devices except those that allows the Long time function of the device not to be used.

ShortTimeFunction IfcPropertySingleValue IfcBoolean

Applying short time function A flag indicating that the short time function of the device is used. The value should be set to FALSE for devices not having a short time function, or if the short time function is not selected to be used.

ShortTimei2tFunction IfcPropertySingleValue IfcBoolean

Applying short time i2t function. A flag indicating that the I2t short time function of the device is used. The value should be set to TRUE only if the I2t function  is explicitly selected for the device.

GroundFaultFunction IfcPropertySingleValue IfcBoolean

Applying ground fault function. A flag indicating that the ground fault function of the device is used. The value should be set to FALSE for devices not having a ground fault function, or if the ground fault function is not selected to be used.

GroundFaulti2tFunction IfcPropertySingleValue IfcBoolean

Applying ground fault i2t function. A flag indicating that the I2t ground fault function of the device is used. The value should be set to TRUE only if the I2t function is explicitly selected for the device.

LongTimeCurrentSetValue IfcPropertySingleValue IfcElectricCurrentMeasure

Long time current set value. The set value of the long time tripping current if adjustable.

ShortTimeCurrentSetValue IfcPropertySingleValue IfcElectricCurrentMeasure

Short time current set value. The set value of the long time tripping current if adjustable.

InstantaneousCurrentSetValue IfcPropertySingleValue IfcElectricCurrentMeasure

Instantaneous current set value. The set value of the instantaneous tripping current if adjustable.

GroundFaultCurrentSetValue IfcPropertySingleValue IfcElectricCurrentMeasure

Ground fault current set value. The set value of the ground tripping current if adjustable.

LongTimeDelay IfcPropertySingleValue IfcTimeMeasure

Long time delay. The set value of the long time time-delay if adjustable.

ShortTimeTrippingTime IfcPropertySingleValue IfcTimeMeasure

Short time tripping time. The set value of the short time tripping time if adjustable.

InstantaneousTrippingTime IfcPropertySingleValue IfcTimeMeasure

Instantaneous tripping time. The set value of the instantaneous tripping time if adjustable.

GroundFaultTrippingTime IfcPropertySingleValue IfcTimeMeasure

Ground fault tripping time. The set value of the ground fault tripping current if adjustable.
