DPB02CM48

Overview

The Carlo Gavazzi DPB02CM48 is a three-phase monitoring relay designed for industrial applications. It detects phase loss, incorrect phase sequence, and voltage anomalies in AC systems operating between 380VAC and 480VAC. The unit features screw terminals for both coil and contact connections, facilitating secure DIN rail mounting. It utilizes SPDT contacts rated at 8A @ 250VAC to trigger protective actions. The device operates within a temperature range of -20°C to 50°C and carries an IP20 protection rating, ensuring reliable performance in standard electrical control panels.

Feature Summary

• Detects total or partial phase loss and incorrect phase sequence in three-phase power supplies
• Features non-latching relay contacts with screw terminal connections for secure wiring
• Designed for direct DIN rail installation in industrial control environments

Applications

• Protection of three-phase motors against phase failure
• Monitoring HVAC systems using low-GWP refrigerants
• Industrial machinery requiring reliable three-phase power supervision

Procurement Notes
