ABB’s 580 Series 4X Drives – Built for Extreme Environments

ABB has introduced a standard NEMA 4X enclosure for their 580 series drives, suitable for HVAC and water/wastewater applications. Designed for outdoor use, the IP66/UL Type 4X drive is UV and weather-resistant, providing superior protection against corrosion and extreme environments. This enclosure allows for installation near the application, eliminating the need for electrical rooms.

Corrosive Environments

The 580 Series 4x drives’ chemical resistance allow ACQs to withstand corrosive environments containing biocides, ammonia and chlorine. IP66/UL Type 4X ensures ACHs, associated with cooling tower operations, remain efficient and reliable thanks to their corrosion inhibitors.

Weather Exposure

Typical weather exposure for drives on air handlers and other outdoor installations can include freezing temperatures, intense heat, UV, rain and salt spray. ABB’s IP66/UL Type 4X drives deliver dependable operation even in extreme environments.

Essential Features


• DC choke for harmonic mitigation
• Integrated EMC C2 filter
• Coated boards
• Safe torque off (STO)
• Optional robust input disconnect (+F254) to simplify installation
• Two option slots for expanded IO or Fieldbus communications
• Optional Bluetooth control panel; can be used up to 250 ft (75m) away


  • Water specific software
  • Standard water specific primary settings
  • Dedicated pump/blower software features used throughout the ACQ580 drive series (cavitation control, pump clean, soft pipe fill, multi-pump control and more)
  • Speaks your language: ACQ580 uses a water dedicated control panel

An optional fused disconnect simplifies installation. This robust UL98 disconnect eliminates the need for branch circuit fuses while maintaining 100 kA SCCR.
