Belimo ARB24-3-S 24V 180 in-lb On/Off Floating Point NEMA 2X Actuator

The Belimo ARB24-3-S is a 24V non-spring return electric damper actuator designed for reliable, precise control of HVAC dampers in commercial and industrial applications. This versatile actuator features 180 in-lb of torque and operates in on/off or floating point control modes, making it ideal for modulating dampers in VAV systems, air handlers, and exhaust systems.

Key Features:

• 24V AC/DC power supply for flexible installation
• 180 in-lb (20 Nm) torque output for positive damper control
• Non-spring return operation for energy-efficient positioning
• On/off and floating point control modes
• Built-in auxiliary switch for position feedback and interlock functions
• NEMA 2X rated enclosure for protection against dripping water and dust
• Reversible motor for clockwise or counterclockwise operation
• 90-second nominal running time for quick response
• Direct-coupled mounting for easy installation

The integrated auxiliary switch provides end position indication and enables integration with building automation systems. The NEMA 2X enclosure rating ensures reliable operation in challenging environments while the non-spring return design reduces energy consumption. Compatible with standard Belimo mounting kits and linkages for universal damper shaft connection.
