Product details

75 kW HVAC drive with integrated safety

The Schneider Electric ATH630D75N4Z is a 75 kW normal duty (55 kW heavy duty) AC drive from the Altivar HVAC ATH600 series, designed for variable-speed control of pumps, fans, and compressors in building HVAC and industrial air-handling systems. Rated for 131.3 A line current at 380 V (normal duty) and 86.9 A at 480 V (heavy duty), this drive handles the full range of motor loads up to 100 hp in standard applications.

Ratings that decide the fit

The dual-duty rating — 75 kW normal duty for variable-torque loads like centrifugal fans, 55 kW heavy duty for constant-torque loads like conveyors or screw compressors — means one drive covers both classes without oversizing. Integrated Safe Torque Off (STO) to SIL 3 / PL e eliminates the need for a separate safety contactor on the motor circuit, reducing panel wiring and cabinet space. Built-in Class C3 EMC filter meets EN/IEC 61800-3 for industrial environments — no external filter needed for most installations, saving a DIN-rail slot and a cable gland.

Application-specific functions

Fire mode, forced fire mode, and damper control are built into the firmware — no option card needed for smoke-extract or pressurisation sequences in life-safety systems. Underload detection for broken belt and scroll compressor management protect the driven equipment from mechanical faults before they cause motor damage. Catch on the fly lets the drive synchronise to a spinning motor after a momentary power loss — useful for fan banks where the rotor is still turning when the supply returns.

Sourcing and compliance

Carries CE, UKCA, CULus, EAC, RCM, ATEX, and KCC markings, with RoHS and WEEE compliance — accepted across European, North American, Eurasian, and Korean regulatory jurisdictions. Full documentation package includes UL 61800-5-1 and IEC 61800-3 certification, plus IEC 61508 SIL 3 safety case — the paperwork for a plant-wide safety audit is on file.

Frequently asked questions

What safety functions does the ATH630D75N4Z include?

Safe Torque Off (STO) rated SIL 3 per IEC 61508 and PL e per ISO 13849-1, eliminating the need for an external safety contactor in most guarding circuits.

What is the difference between normal duty and heavy duty on this drive?

Normal duty is 75 kW (100 hp) for variable-torque loads like centrifugal fans and pumps; heavy duty is 55 kW (75 hp) for constant-torque loads such as conveyors, screw compressors, or positive-displacement pumps.
