Product Information
Extended Description
3AXD50000956845 ABB: The ACH180 HVACR compact drive modules provide the quality, reliability, and energy savings you expect, while offering essential HVACR features, being compact and easy to fit tight spaces. They are simple to use and safe to maintain. All you need to do is to set the drive up, and then focus on what counts. Everything you need, nothing you don't.
IEC-rated power handling at 18.5 kW (400 V) preserves full torque for larger HVACR loads, enabling fast startup and smooth operation even on variable loads. This translates to improved climate control, reduced compressor cycling, and measurable energy savings in commercial buildings. UL-rated performance up to 25 Hp at 460 V delivers proven safety and reliability in critical systems. The UL compliance simplifies commissioning to building codes and procurement requirements, reducing risk during retrofits and new installations. The compact footprint is designed for tight panel spaces, easing installation and minimizing cabinet alterations in retrofit projects. Easy setup and safe maintenance support rapid commissioning and higher uptime, while predictable motor control reduces wear on pumps and fans. Energy-efficient operation and scalable performance make it easier to justify upgrades during system modernization.

FAQs
This drive is designed for panel-mount installation with a compact footprint to fit tight spaces common in HVACR equipment. Plan for 400 V IEC operation and 460 V UL operation, ensuring wiring meets local codes and proper clean, shielded cables are used to minimize EMI. Verify mounting clearance, cable routing, and sufficient ventilation to maintain optimal performance and long service life.
For IEC operation, the drive handles 18.5 kW with 38 A at 400 V. The UL specification covers up to 25 Hp at 460 V with 34 A. These dual rating points enable flexible selection for different motor strings and supply configurations, supporting both high-torque startup and efficient continuous operation in variable HVAC loads.
Yes. The ABB micro drive module is designed for low-voltage HVACR motors typical in air handling units, rooftop units, and pumps. It provides precise speed control, smooth acceleration/deceleration, and integration with standard control systems, enabling improved temperature stability, reduced energy use, and extended equipment life in renovated or new-build applications.
The device is UL-listed for safety, with IEC-based electrical ratings supporting compliant operation in many regions. This combination helps simplify procurement, minimizes regulatory risk during commissioning, and improves consistency with existing HVACR standards in commercial and industrial facilities.
Energy savings from optimized speed control reduce operating costs, while a compact, robust design lowers installation time and panel footprint. The simplified setup and reliable UL/IEC-rated performance contribute to lower maintenance needs and fewer field service calls, delivering a favorable return on investment over the life of the HVACR system.
