Product details

The Schneider Electric ATH630U15N4Z is a current-production Altivar HVAC drive from the ATH600 series, sized for a 1.5 kW motor at normal duty or 0.75 kW at heavy duty on a 380-480 V three-phase supply. It carries a Class C2 EMC filter integrated, STO safety function rated SIL 3 / PL e, and the usual HVAC-specific firmware — fire mode, PID, damper control, scroll compressor management.

The normal-duty line current is 3.463 A at 380 V and 2.7 A at 480 V; heavy-duty drops to 2 A at 380 V and 1.7 A at 480 V. That 1.5 kW / 0.75 kW split is the key selection gate — if your motor is a constant-torque load (conveyor, positive-displacement pump), you size to the heavy-duty column; for variable-torque HVAC loads (fan, centrifugal pump), normal duty applies. The drive needs a 24 V DC external control supply (19...30 V) and provides internal 24 V for digital inputs and STO. Mounts in a cabinet, vertical position only, with derating above 1000 m altitude.
