Three basic devices (PKE12 for up to 12 A, PKE32 for up to 32 A, and PKE65
for up to 65 A) and six different electronic trip blocks make it possible to
monitor motors with a rated motor current range of 0.3 to 65 A (￫ table 1).
The rated operational current and the tripping class must be set on all trip
blocks PKE-XTU(W)(A)-...
In addition, PKE-XTU(W)A-... trip blocks can be used to transmit operational
data (such as instantaneous current values and trip reasons) to a higher-level
field bus system via SmartWire-DT. These communication tasks do not
affect the device's motor protection function in any way.
