Schneider Electric (Barber Colman) MA-419-500 Actuator

The Schneider Electric Barber Colman MA-419-500 is an industrial-grade, 240V two-position actuator engineered for heavy-duty damper and valve control. This spring return actuator provides 60 lb-in of torque and is specifically designed to return equipment to its normal position immediately upon power interruption. As the direct replacement for the obsolete MA-419-191, this model now includes a weatherproof gasket as a standard feature, enhancing its durability in varied environments. It utilizes an oil-submerged motor and gear train housed in rugged die-cast aluminum to ensure consistent performance under high-demand cycles. The integration of a built-in SPDT auxiliary switch allows for precise end-point signaling or interlocking with secondary equipment. Designed for horizontal mounting of the output shaft, this unit draws 70 watts during active running and 25 watts while holding. For contractors maintaining legacy systems, the MA-419-500 electric actuator offers a reliable mechanical movement solution for rotary requirements in complex HVACR infrastructures.

• Enhanced Durability: Features an oil-immersed motor and gear train within a die-cast aluminum housing for long-term mechanical reliability.
• Fail-Safe Operation: True spring return functionality ensures dampers or valves transition to a safe state during power loss.
• Advanced Protection: Now includes a standard weatherproof gasket, providing superior resistance to environmental moisture compared to legacy models.
• Integrated Logic: The SPDT auxiliary switch (suffix -500) enables easy integration for motor status feedback or auxiliary device control.
• High Torque Output: Delivers a consistent 60 lb-in torque suitable for larger damper assemblies and globe valve applications.

Is the MA-419-500 a direct replacement for the MA-419-191?
Yes, the MA-419-500 is the official replacement for the MA-419-191 and includes the upgraded weatherproof gasket as standard.

What are the mounting requirements for this actuator?
To ensure proper lubrication of the oil-submerged components, the actuator must be mounted with the output shaft in a horizontal position.

What is the difference between the -500 and base models?
The -500 suffix indicates the inclusion of an internal SPDT auxiliary switch, which is not present on standard two-position models in this series.
