Belimo NMB24-3 24V Non-Spring Return Damper Actuator 70 in-lb Floating Control

The Belimo NMB24-3 is a robust non-spring return damper actuator designed for commercial HVAC applications requiring on-off or floating point control. This actuator delivers 70 in-lb (8 Nm) of torque, making it suitable for controlling small to medium-sized dampers in air handling systems.

Key Features:

• 24V AC/DC power supply for flexible installation options
• 70 in-lb (8 Nm) torque output for reliable damper positioning
• On-off or floating point control for versatile system integration
• Non-spring return operation maintains position during power loss
• 95-second running time for full 90-degree rotation
• Direct replacement for legacy NM-24 US and NM24 US models
• Auxiliary switches for position feedback and control sequencing
• Durable construction for long service life in demanding environments

This actuator is ideal for zone damper control, economizer dampers, and general ventilation applications where precise airflow control is required. The floating point control capability allows for modulating control when paired with compatible building automation systems. Mounting hardware and universal mounting bracket included for easy installation on various damper types.
