Positive Active Energy phase B
Positive Active Energy phase C
Negative Active Energy phase A
Negative Active Energy phase B
Negative Active Energy phase C
3-phase only positive Active Energy
3-phase only negative Active Energy
Positive Reactive Energy phase A
Positive Reactive Energy phase B
Positive Reactive Energy phase C
Negative Reactive Energy phase A
Negative Reactive Energy phase B
Negative Reactive Energy phase C
3-phase only positive Reactive Energy
3-phase only negative Reactive Energy

S203TA-D Insertion types
The following insertion types are possible (CT = current transformer, VT = voltage transformer):
Single phase insertion
Single phase insertion with CT
Single phase insertion with VT
Single phase insertion with CT and VT
Aron insertion with CTs
Aron insertion with CTs and VTs
3-phase insertion with neutral with CTs
3-phase insertion without neutral with CTs
3-phase insertion without neutral with CTs and VTs
WARNING!
ARON insertion without CTs it’s not allowed (two phases are short circuited!)
3-PHASE insertion without CTs it’s not allowed (the phases are short circuited!)
