Why Choose the Carlo Gavazzi PPC01DM48 3-Phase Monitoring Relay?
The Carlo Gavazzi PPC01DM48 is a versatile three-phase multifunction monitoring relay designed to monitor industrial electrical supplies for phase loss, incorrect phase sequence, overvoltage, undervoltage, voltage asymmetry and voltage tolerance conditions. As part of the Carlo Gavazzi PPC01 monitoring relay series, it provides comprehensive supervision of three-phase power systems used in industrial automation, machinery and electrical control applications.
The relay is designed for 380–480 V AC three-phase supplies and operates at 50–60 Hz. The PPC01DM48 supports selectable nominal voltage ranges covering 380–415 V AC and 440–480 V AC systems, with the monitored three-phase supply providing the relay's operating power. It can detect phase sequence and phase loss while also monitoring voltage levels, asymmetry and tolerance.
The PPC01DM48 provides two SPDT electromechanical relay outputs, allowing separate control or alarm functions from the monitored conditions. Adjustable voltage and asymmetry/tolerance thresholds, together with alarm delays from 0.1 s to 30 s, provide flexible configuration for industrial applications. Its compact 36 mm wide plug-in housing is designed for an 11-pin socket.

Reliable Three-Phase Power Monitoring for Industrial Systems
Three-phase monitoring relays continuously supervise electrical supplies and provide a control response when abnormal phase or voltage conditions are detected. This helps automation systems identify missing phases, incorrect phase sequence, excessive voltage imbalance and voltage deviations before these conditions can adversely affect connected machinery.
The Carlo Gavazzi PPC01DM48 uses the monitored three-phase supply as its power source and provides configurable monitoring of phase sequence, phase loss, voltage level, asymmetry and tolerance. Its adjustable setpoints and alarm delays allow the relay to be configured for different industrial electrical systems and protection requirements.
