FAQs
This drive is designed for three-phase LV networks up to 400 V. Ensure correct three-phase wiring, proper enclosure clearance for heat dissipation, and compliant cable routing. Use shielded control cables where indicated and follow ABB installation guides to set up nominal current (32 A) and motor protection settings. Proper fusing and grounding are essential to minimize electrical noise and protect protection relays.
Key specifications include a nominal power rating of 15 kW (Pn), maximum input current around 32 A at 400 V, and UL-listed performance equivalent to 20 Hp at 460 V for certain configurations. These metrics enable reliable speed control for HVACR loads such as fans and pumps, with smooth acceleration and deceleration to reduce mechanical stress.
Yes. The ACH180-based drive module supports HVACR applications requiring precise motor control, smooth ramping, and reliable protection in tight spaces. It is well-suited for air handling units, rooftop units, and circulating pumps where energy efficiency and compact installation are priorities, provided the load current and voltage specifications align with 32 A at 400 V.
The drive carries UL-listed safety credentials and is designed to meet IEC-based performance expectations common for HVACR drives. Always verify the latest datasheet for any region-specific markings (such as CE where applicable) and confirm compatibility with local electrical codes before deployment.
The module offers energy-efficient motor control, reducing running costs in HVACR applications by smoothing starts and reducing fan/pump load surges. Its compact design lowers cabinet space and simplifies wiring, which cuts installation time. With robust protection features and a proven ABB reliability baseline, maintenance intervals can be extended, improving uptime and total cost of ownership.
