Schneider Electric (Barber Colman) MP-2130-500 Proportional Actuator

The Schneider Electric MP-2130-500 is an industrial-grade proportional actuator engineered for precise modulation of dampers and valves in commercial HVAC and building automation systems. Operating on 120V AC, this high-performance unit delivers a solid 50 lb-in torque suitable for small and medium-sized air handling applications. As a non-spring return actuator, it maintains its last position upon power loss, providing stable control and reducing mechanical stress on linkages. The unit offers a standard 90-degree rotation with a fast no-load timing of approximately 25 seconds, ensuring responsive adjustment to control signals.

This Barber Colman MP-2130-500 is architecturally identical to the EA-21 and EA-23 series, making it a reliable drop-in replacement for legacy field installations. It features a built-in SPDT auxiliary switch for position feedback or interlocking with secondary equipment, and utilizes rugged screw terminal connections for secure field wiring. Designed for durability in demanding environments, it operates effectively within a temperature range of -40 to 136°F, carrying a NEMA 1 rating for protected indoor installations.

Key Technical Benefits

• Universal Field Compatibility: Direct replacement for EA-21 and EA-23 actuators, simplifying retrofit projects.
• Precision Modulation: Optimized for proportional control signals to maintain exact airflow and temperature setpoints.
• Integrated Feedback: Features a factory-installed SPDT auxiliary switch for status monitoring or sequencing control.
• Industrial Build Quality: Heavy-duty construction handles 50 lb-in torque requirements with consistent timing performance.

Common Contractor Questions

Is the MP-2130-500 compatible with older Barber Colman systems?
Yes, this model is the direct modern equivalent to the EA-21 and EA-23 series and is fully compatible with existing proportional control loops and linkages.

Can this actuator be used in failsafe applications?
This is a non-spring return actuator. For applications requiring a return-to-zero position upon power failure, a spring-return model or an external power backup system is required.

What is the maximum torque capacity for damper shafts?
The unit is rated for a 50 lb-in torque. Always calculate the damper's square footage and friction coefficient to ensure the load does not exceed this rating.
