Carlo Gavazzi Monitoring Relay Voltage 3-Phase Plug-In PPB01CM44

Carlo Gavazzi Monitoring Relay Voltage 3-Phase & 3-Phase+N, Over & Under Voltage, Phase Loss & Sequence, SPDT, Plug-In, Supply: 208-480Vac, 50-400Hz.

DPB01 and PPB01 are 3-phase mains monitoring relays, they operate on 3P and 3P+N systems, monitoring phase loss and phase sequence (not present in versions with "N" ending), overvoltage and undervoltage. Power supply provided by the monitored mains. Delay on alarm up to 30s for over/under voltage alarms. DPB01 and PPB01 offer solutions for a wide range of applications: lifts, escalators, HVAC, material handling, pumps, compressors, and mobile machinery installations.

General Characteristics

• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).
• Detection of the correct phase sequence (not present in versions with "N" ending) and phase loss.
• Front dial adjustable overvoltage and undervoltage setpoints.
• SPDT, Changeover relay output.
• Wide voltages and frequency ranges, working in systems from 208 to 480 VAC and 50 to 400Hz.
• Adjustable voltage levels 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 (DPB01) and Plug-in (PPB01) mounting.
• Adjustable delay function, 0.1 to 30s.
• Adjustable power ON delay, to avoid nuisance tripping at start-up.
• Ultra-high harmonic immunity. For very noisy environments
