Schneider Electric MS40-7173 24V Proportional Spring Return Actuator 150 lb-in

The Schneider Electric (Barber Colman) MS40-7173 is a direct-mounted electric actuator designed for precise control of HVAC dampers and valves. This proportional spring return actuator operates on 24V power and delivers 150 lb-in of torque, making it ideal for commercial building automation applications.

Key Features:

• 24VAC/VDC power supply for flexible installation
• 150 lb-in torque rating for reliable damper control
• Proportional control for precise modulation
• Spring return mechanism for fail-safe operation
• Direct mount design simplifies installation
• Compatible with standard damper linkages
• Compact footprint for space-constrained applications

The spring return function ensures the actuator automatically returns to its home position during power loss, providing critical fail-safe protection for your HVAC system. The proportional control allows for smooth, variable positioning based on control signal input, enabling precise temperature and airflow management.
