DPB02 and PPB02 are 3-phase mains monitoring relays.

They operate on 3P and 3P+N systems, monitoring phase loss, phase sequence and voltage asymmetry.

Power supply provided by the monitored mains.

Delay on alarm, up to 30s, for asymmetry alarm.

Benefits

• Wide voltages and frequency ranges. Working in systems from 208 to 480 VAC and 50 to 400Hz.

• Adjustable voltage asymmetry level and time delay. To allow a correct response to real alarm conditions.

• Output and status LED indication. For quick troubleshooting.

• Two mounting versions. Available for DIN-rail (DPB02) and Plug-in (PPB02) mounting.

• Adjustable power ON delay. To avoid nuisance tripping at start-up.

• Ultra-high harmonic immunity. For very noisy environments.
