Honeywell MS4604F1010 Spring Return Damper Actuator - 230V

The Honeywell MS4604F1010 is a spring return damper actuator designed for fire and smoke control applications in commercial HVAC systems. This 230-volt actuator provides reliable motorized control of fire/smoke dampers with 30 lb-in (3.4 Nm) of torque output.

Key Features:

• 230VAC power supply for European and international applications
• 30 lb-in torque rating for medium-duty damper control
• Spring return mechanism ensures fail-safe damper positioning during power loss
• 2-position control (open/closed) with end switches
• Direct-coupled mounting for easy installation on fire/smoke dampers
• Durable construction for commercial building environments
• Designed for life safety applications requiring reliable damper control

This actuator is commonly used in fire-rated damper assemblies where automatic closure is required during fire alarm conditions. The spring return function provides fail-safe operation by returning the damper to its safe position when power is removed or during emergency situations.
