Product details

400 hp at 480 V — normal and heavy duty defined

The ATH630C25N4Z is a cabinet-mount Altivar 600 drive rated 400 hp (250 kW) for normal duty and 300 hp (200 kW) for heavy duty at 480 V. The normal-duty line current is 451 A at 380 V and 366 A at 480 V; heavy duty draws 365 A at 380 V and 301 A at 480 V. Apparent power is 304.3 kVA normal duty, 250.2 kVA heavy duty.

Safety integration and EMC compliance

Built-in STO (safe torque off) function certified to SIL 3 per IEC 61508 and PL e per ISO 13849-1, so the drive can serve in safety circuits without an external safety relay for the stop function. The integrated Class C3 EMC filter meets EN/IEC 61800-3 for second-environment (industrial) installations, meaning an external filter may be needed for residential or first-environment mains.

HVAC-specific firmware and fieldbus options

The drive includes fire mode, forced fire mode, PID controller with three additional PID loops, damper control, scroll compressor management, and catch-on-the-fly — functions that match the Altivar 600's HVAC positioning. Communication options include BACnet IP, PROFINET, and Ethernet IP/Modbus TCP via option cards, plus a built-in 2-wire RS-485 with Modbus RTU and BACnet MS/TP.

Frequently asked questions

What compliance documentation does Schneider Electric provide for ATH630C25N4Z?
