Carlo Gavazzi PPB02CM48 3-Phase Monitoring Relay

Carlo Gavazzi PPB02CM48 is a 3-phase voltage monitoring relay designed to protect motors and other three-phase loads by detecting phase loss, phase sequence errors, and voltage asymmetry on 380–480 VAC power systems (440–480 VAC variants). Housed in a 36 mm plug-in module, it mounts quickly and provides a single SPDT relay output to drive contactors, alarms, or control circuits. It operates at 50–60 Hz and offers an alarm delay adjustable from 0.1 to 30 seconds to suit different protective schemes, with regenerated voltage detection to sense back-fed or recovered voltages after a fault. The PPB02CM48 is CE certified with approvals for Europe, North America, and Australia, and carries E-Numbers 4367593 (Norway) and 3864699 (Sweden). This compact monitoring relay is intended for plug-in installation and delivers a straightforward, reliable protection option when precise phase monitoring is required in industrial environments.
