Description

Carlo Monitoring Relay 3 phase type DPB02CM48 DPB02, PPB02 True RMS 3-Phase voltage monitoring relay

3-Phase Star-Delta True RMS Monitoring Relay, Asymmetry, Sequence and Phase Loss, 1 SPDT Relay Output, IP20, DIN-rail mounting, Measuring Range 323 to 550Vac, 22.5×83,5×99.5mm housing.

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

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 30 s, for asymmetry alarm.

• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).
• Detection of the correct phase sequence and phase loss.
• Front dial adjustable voltage asymmetry setpoint.
• Time delay.
• Changeover relay output.
