Product Description
DPA51 and DPA71 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. It has a space-saving design for DIN rail mounting.
- Wide voltage range: The monitoring relay range spans 208 to 480 VAC.
- 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
- Very compact: 17.5 mm (DPA51) and 35.5 mm enclosure (DPA71) for DIN rail mounting
- Three-line three-phase mains monitoring (3P)
- Detection of the correct phase sequence and phase loss
- Centre-zero relay output
