Barber Colman MA-418 120V Spring Return Electric HVAC Actuator 60 lb-in Torque

Description

The Barber Colman MA-418 is a spring-return electric actuator designed for two-position control of dampers and mechanical equipment in commercial and industrial HVAC systems. Barber Colman part number MA-418 operates on 120 VAC single-phase power and provides 60 lb-in of torque for reliable positioning of connected equipment. Its spring-return mechanism automatically moves the actuator toward its normal position when electrical power is removed.

Technical Specifications

Information About MA-418

The MA-418 is a Barber Colman electric actuator designed for on/off positioning applications in heating, ventilation, and air conditioning control systems. Its electromechanical construction combines a 120 VAC motor drive with a mechanical spring-return mechanism, allowing powered movement in one direction and automatic return when the supply is interrupted. The actuator operates at 60 Hz and provides 60 lb-in of rated torque, with electrical consumption of 70 W during operation and 25 W while holding position. Designed for integration with compatible damper assemblies and mechanical linkages, the unit supports building automation applications requiring two-position control and automatic return functionality.

Key Features:

• Spring-Return Operation: Automatically returns the actuator toward its normal position when electrical power is removed.

• 60 lb-in Torque Output: Provides mechanical force for positioning compatible HVAC dampers and control mechanisms.

• 120 VAC Power Supply: Operates from standard 120 VAC single-phase electrical power.

• Two-Position Control: Supports fully open and fully closed positioning in compatible HVAC control applications.

• 60 Hz Frequency: Designed for operation with 60 Hz electrical supply systems.

• 70 W Running Consumption: Uses approximately 70 watts during powered actuator movement.

• 25 W Holding Consumption: Requires approximately 25 watts to maintain its energized position.

• Electromechanical Drive: Combines an electric motor and spring mechanism for controlled movement and automatic return.

• HVAC Damper Compatibility: Intended for integration with suitable air-handling dampers and mechanical control linkages.

• Power-Loss Return: Provides automatic mechanical repositioning when the electrical supply is interrupted.

• Industrial Control Application: Suitable for building automation, ventilation control, and HVAC equipment operation.

• American Manufacturing: Identified as a USA-manufactured Barber Colman actuator.

The MA-418 delivers the reliability and precision required for two-position HVAC damper control, ventilation system operation, and spring-return mechanical positioning.
