Product details

Dual-duty power ratings and line current

The ATH630D22N4Z is a 22 kW (30 hp) normal-duty drive with a heavy-duty rating of 18.5 kW (25 hp). The normal-duty line current is 39.6 A at 380 V and 34 A at 480 V; heavy-duty line current drops to 34.1 A at 380 V and 29.9 A at 480 V.

Safety and compliance stack

Safe Torque Off (STO) is built in, certified to SIL 3 per IEC 61508 and PL e per ISO 13849-1. That eliminates the need for an external safety relay on the motor power circuit for most guarding applications. The integrated Class C2 EMC filter covers conducted emissions for first-environment (residential) installations, so you do not need an add-on filter for most European and UKCA markets.

Application-specific firmware features

This drive ships with HVAC-specific functions: fire mode, forced fire mode, damper control, broken-belt detection via underload, scroll compressor management, and skipped frequencies to avoid mechanical resonances. The PID controller supports three additional PID sets, useful for multi-zone pressure or temperature control. Catch on the fly lets it re-synchronise to a spinning motor without a coast-to-stop cycle.

Frequently asked questions

What safety functions does the ATH630D22N4Z include?

Safe Torque Off (STO) is integrated and certified to SIL 3 (IEC 61508) and PL e (ISO 13849-1). This covers the motor power removal function for most guarding circuits without an external safety relay.

What compliance markings does the ATH630D22N4Z carry?

CE, UKCA, CULus, EAC, RCM, ATEX, WEEE, ROHS, and KCC. The drive also meets 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.

How can I order the ATH630D22N4Z or check availability?

This drive is sourced to order against the BOM quantity. Submit an RFQ for current pricing and lead time; availability is confirmed at quote time through independent distribution channels.
