Product details

The ATH630D30N4Z is a 30 kW normal-duty / 22 kW heavy-duty HVAC drive from the Altivar ATH600 series, built for fan, pump, and compressor loads in commercial building services. Line current at 380 V normal duty is 53.3 A; at 480 V heavy duty it drops to 35.8 A — the lower current at higher line voltage means the drive's thermal capacity is set by the 380 V normal-duty figure for sizing the input protection. Integrated Class C2 EMC filter means the drive meets the conducted-emission limits for the second environment (industrial) without an external filter, which simplifies panel layout and saves a DIN-rail slot. The STO (safe torque off) function is certified SIL 3 per IEC 61508 and PL e per ISO 13849-1, so it can be wired directly into a safety circuit that removes drive torque without a separate safety contactor — provided the control wiring meets the SIL 3 segregation rules.

Panel fit and fieldbus options

The drive ships with a 2-wire RS-485 physical interface supporting Modbus RTU and BACnet MS/TP at selectable baud rates up to 76.8 kbit/s — the native BACnet connectivity is what makes this an HVAC-specific variant rather than a general-purpose Altivar. Optional communication modules snap into the option-card slot for PROFINET, Ethernet IP/Modbus TCP, or BACnet IP — if the BMS backbone is Ethernet, order the appropriate card at the same time to avoid a second panel visit.

Frequently asked questions

What compliance documentation does Schneider provide for ATH630D30N4Z?

The drive carries CE, UKCA, CULus, EAC, RCM, ATEX, WEEE, RoHS, and KCC markings, and is certified to UL 61800-5-1, EN/IEC 61800-3, EN/IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and ISO 13849-1. RoHS and REACH declarations are standard with the shipment.

What are the key HVAC-specific functions of this drive?

The firmware includes fire mode, forced fire mode, PID controller with three additional PID loops, damper control, underload detection for broken belt, scroll compressor management, skipped frequencies, catch on the fly, and power monitoring — all built in, no option card required.
