All configuration criteria are coded within the Long Product Code

The first 5 digits define the Device Type device specific base price

The Hardware Configurationis based on common module system common price structure

The Functional Classdefines the number of needed function pointscommon price structure

Significant Property(position 21) define major price offsets device specific Add-On price

which cannot be addressed by function points.

Protection news

Power Swing: Two functions

Power Swing Blocking (ANSI 68)

Avoids uncontrolled tripping of the distance

protection Operates under symmetrical load conditions as

well as during single-pole auto-reclose cycles

Requires no settings

Can be configured separately to block each

distance zone

Evaluates the impedance trajectory of the

positive sequence impedance Provides a response characteristic with up to 4

impedance zones in the R/X plane

Operates independently from settings of distance

protection zones

Increments counters depending on the point at

which the impedance trajectory enters or exits

the associated impedance zone

Out-of-step protection (ANSI 78)
