Belimo GMX120-3 Direct Coupled Actuator 360 in-lb 100-240VAC

The Belimo GMX120-3 is a direct coupled rotary actuator designed for precision control of dampers and valves in commercial HVAC systems. This robust actuator delivers 360 in-lb of torque, making it suitable for larger damper applications requiring higher force output.

Key Features:

• 360 in-lb (40 Nm) maximum torque output for demanding applications
• Universal voltage operation: 100-240 VAC, 50/60 Hz for flexible installation
• Non-spring return (NSR) design maintains position during power loss
• Direct coupled mounting for space-efficient installation
• 95° nominal rotation for standard damper control
• Durable construction with long service life in commercial environments
• Manual override capability for service and testing
• Compact footprint for tight equipment room installations

This actuator is ideal for commercial building automation systems requiring reliable, high-torque damper control. The non-spring return design makes it well-suited for applications where maintaining damper position during power interruptions is preferred, such as mixed air dampers, economizer systems, and general ventilation control.
