Schneider Electric MP-371 Spring Return Damper Actuator 24V 50 lb-in

The Schneider Electric (Barber Colman) MP-371 is a spring return damper actuator designed for HVAC zone control applications. This actuator provides reliable, automatic control of dampers in commercial and residential heating, ventilation, and air conditioning systems.

Key Specifications:

• 24V AC/DC power supply for compatibility with standard HVAC control systems
• Spring return operation with counterclockwise (CCW) rotation for fail-safe positioning
• 50 lb-in (5.6 Nm) torque output for effective damper control
• 90-second timing for 180-degree rotation ensures smooth, controlled movement
• Integrated auxiliary switch for position indication and control sequencing
• Compact, durable construction suitable for commercial-grade installations

The spring return mechanism ensures that the damper returns to its normal position during power failure, making this actuator ideal for safety-critical applications and zone control systems. The included auxiliary switch enables integration with building automation systems and provides feedback for control verification.
