FAQs
The 3AXD50000956746 is designed to drive standard low-voltage HVAC motors up to 7.5 kW and 230 V, aligning with typical commercial and industrial fan and pump specifications. It simplifies wiring by using conventional LV AC motor interfaces and integrates smoothly with common control panels used in air handling units. For retrofits, confirm motor nameplate current and ensure the power feeder has adequate headroom; ABB’s ACH180 family interface provides a familiar control language and parameter mapping to minimize reprogramming.
Key specifications include 7.5 kW (10 HP) power, 32 A current at 230 V, and a UL-listed HVACR-ready profile. By enabling precise speed control, the drive minimizes fan and pump over-speed and smooths acceleration, reducing energy use across partial-load conditions. This translates to lower utility costs, extended motor life due to reduced mechanical stress, and better process stability in variable HVAC loads.
Yes. The 3AXD50000956746 LV AC micro drive is specifically positioned for HVACR applications, including air handling units and fan-driven systems. Its compact form, 230 V operation, and the ability to tune speed profiles support quieter operation, improved zone control, and energy savings in AHUs and cooling towers. It also benefits retrofit projects where space and wiring efficiency matter most.
The drive is UL-listed for HVACR usage, a critical certification that underpins safety and reliability in commercial and industrial environments. UL recognition helps with regulatory compliance, safer motor control integration, and consistent performance under HVAC duty cycles. Understanding these certifications supports risk mitigation in procurement and project approvals.
Expected ROI comes from energy savings through optimized motor speed, reduced mechanical wear, and lower maintenance downtime due to simpler commissioning. The compact installation reduces panel space and wiring costs, while ABB’s ACH180 ecosystem delivers consistent performance across units. Over a typical HVAC project, these factors combine to shorten payback periods and improve overall system reliability.
