Schneider Electric (Barber Colman) MA-5210-500 Hydraulic Actuator

The Schneider Electric (Barber Colman) MA-5210-500 is an industrial-grade two-position hydraulic actuator engineered for reliable on/off control of valves and dampers in demanding HVACR environments. Operating on 120V AC, this unit features a robust oil-immersed motor and pump assembly housed in a NEMA 1 enclosure. The 15-second spring return provides a critical fail-safe, ensuring the connected valve or damper moves to its normal position immediately upon power interruption. Integrated with a factory-set SPDT auxiliary switch, this actuator allows for seamless end-of-stroke signaling or the interlocking of secondary equipment like fans or pumps.

Designed for professional contractors, the MA-5210-500 actuator delivers a high-torque 18VA input (14 Watt) performance with a linear stroke that is compatible with AV-600 valve linkages and AM-601 damper linkages. Its die-cast lower housing and painted steel upper casing are built to withstand standard mechanical room conditions while providing precise 2-position control. Whether you are performing a Barber Colman actuator replacement or a new 120V HVAC installation, this hydraulic unit is the standard for long-term consistency in fluid and airflow management.

• Fail-Safe Reliability: Features a high-tensile 15-second spring return mechanism for immediate safety position during power loss.
• Enhanced System Integration: The built-in SPDT auxiliary switch (10 Amp rated) provides easy feedback for system status monitoring.
• Industrial Construction: Oil-immersed internal components reduce friction and wear during heavy-duty cycling.
• Versatile Compatibility: Mounts directly to Globe Valves and HVAC dampers with industry-standard Schneider mounting brackets.

What is the typical timing for the stroke?
The MA-5210-500 is rated for a 15-second spring return stroke and approximately 60 seconds to fully extend at room temperature (72°F).

Can this replace the older Barber Colman MA-5210-0-0-2 series?
Yes, this model is the technical successor for obsolete 5210 series actuators used in legacy Barber Colman control systems.

Is this suitable for outdoor installation?
The unit is rated for NEMA 1 locations. For outdoor or wash-down environments, a secondary protective enclosure is required to prevent moisture ingress.
