PPA01
Product Description
3-phase relay for detection of
incorrect phase sequence,
total and partial phase loss.
Supply range from 208 to 690
VAC covered by two multi-
voltage relays.
For mounting on DIN-rail or
plug-in module. The device
detects regenerated voltages
up to 85% of the nominal
voltage (phase-phase).
