Schneider Electric MA-305 24V Spring Return Damper Actuator

The Schneider Electric (Barber Colman) MA-305 is a 24-volt, 2-position spring return damper actuator designed for HVAC air control applications. This electric actuator provides reliable on/off damper positioning in commercial and industrial heating, ventilation, and air conditioning systems.

Key Features:

• 24VAC power supply for standard HVAC control integration
• 2-position operation for simple open/closed damper control
• Spring return mechanism automatically returns damper to fail-safe position on power loss
• Compact design suitable for limited installation spaces
• Durable construction for long-term reliability in commercial environments
• Direct mounting to round or rectangular dampers

The MA-305 actuator is ideal for zone control, exhaust air management, economizer control, and other applications requiring reliable two-position damper operation. The spring return feature ensures proper system operation during power failures by automatically positioning the damper to a predetermined safe position.
