The CARLO GAVAZZI PPB01CM44 is a high-performance true RMS 3-phase voltage monitoring relay designed for precise electrical system supervision. Manufactured in Italy, this relay provides reliable detection of phase loss, incorrect phase sequence, overvoltage, and undervoltage conditions across a wide input voltage range.
Key Features:
Wide input voltage range: from 208VAC to 480VAC ±15% (177VAC to 552VAC) with operation up to 400Hz mains frequency.
Adjustable voltage detection: 8 selectable voltage ranges with over/under voltage thresholds adjustable from + or - 2% to 22% of the selected range.
Switch mode power supply: ensures low consumption, minimal heat dissipation, and immunity to mains disturbances, noise, and harmonics.
Visual status indication: yellow LED indicates relay output status; green LED shows power ON status; alarm LED flashes during faults.
Relay contact output: SPDT relay rated at 8A, suitable for remote alarm signaling and control.
Delay on alarm: adjustable from 0.1 to 30 seconds to filter transient conditions.
Enclosure options: DIN rail mounting (DPB01) and Plug-In version (PPB01) compatible with undecal socket.

Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
