The IME MF96421 is a Nemo 96HDLe multifunction energy meter. It is a 96×96 mm panel-mounted instrument designed for single-phase or three-phase (3/4-wire unbalanced) networks, with CT input (1 A or 5 A) and voltage input 80–500 V AC. It measures active energy (Class 0.5) and reactive energy (Class 2) across four quadrants, and provides pulse + RS485 Modbus communication with an additional expansion slot.
