Relays for 3-phase networks

type PSSW1 monitor 3-phase

networks for phase-sequence,

asymmetry and over- and un-

dervoltage.

Applications:Monitoringof 3-pha-

se-networks at heat pumps,

compressors or at machines at

building sites.

Functions:

Over-andundervoltage,adju-

stable ± 2-20 % (common)

Asymmetry adjustable

5-15%

Phase loss

Phase sequence

Switching delay adjustable

0,1-12 s (for voltage and

asymmetry)

Bifrequential measuring input

50/60 Hz

Displays:
