Product Description
The DPA01 and PPA01 are three-phase mains monitoring relays. They can be operated on the 3P mains and detect the correct phase sequence in addition to the phase failure. The supply voltage for the monitoring relays is supplied via the monitored mains.
- Wide voltage range: The monitoring relay range spans 208 to 690 V AC
- LED indicator for operating status, alarm and relay status allows for quick troubleshooting
- Regeneration voltage detection: for detecting phase losses even when the motor is running
- Two mounting versions: available as DIN rail (DPA01) or plugin (PPA01)
- Three-line three-phase mains monitoring (3P)
- Detection of the correct phase sequence and phase loss
- Centre-zero relay output
