The IME MFD45A00 is a Nemo D4-Pt multifunction energy meter. It is a DIN-rail mounted (4 modules) instrument for single-phase or three-phase (3/4-wire unbalanced) networks, with CT input (1–5 A) and voltage input 230–400 V AC. It measures active energy (Class 1) and reactive energy (Class 2) across four quadrants, is self-supplied, and provides a pulse output.
