Schneider Electric (Barber Colman) M312A01 Actuator

The Schneider Electric (Barber Colman) M312A01 is a high-performance 24V floating actuator engineered for precise control of VBB and VBS series valve bodies. Designed as an upgraded SmartX actuator, this unit serves as the direct replacement for M112A01 models, offering an enhanced gear train with stainless steel bearings for long-term reliability in demanding hydronic systems. This spring return normally open actuator ensures the valve returns to its fail-safe position during a loss of power, making it essential for VAV reheat, fan coil units, and unit ventilators.

For seamless integration, the M312A01 actuator features a factory-installed 10' plenum cable and a 3/8" conduit connector, simplifying wiring in plenum-rated spaces. It operates on a 24 VAC supply and is compatible with up to a 60% glycol solution, supporting system static pressures up to 600 psi. The "PopTop" design allows for tool-free installation directly onto the valve body, significantly reducing labor for contractors during field retrofits or new installations.

• Direct M112A01 replacement: Seamlessly upgrades older Barber Colman installations without needing new valve bodies.
• Precision Floating Control: Optimized for stable, accurate flow regulation in hot and chilled water applications.
• Fail-Safe Protection: Reliable spring return normally open (N/O) mechanical operation ensures system safety.
• Plenum Rated: Includes a 10-foot cable and integral conduit fitting for code-compliant installation in ceiling air spaces.
• High Rangeability: Supports a 300:1 rangeability when paired with Schneider VBB/VBS valve series.

Common Questions

Is the M312A01 compatible with older Barber Colman M112A01 setups?
Yes, the M312A01 is the direct engineering successor to the M112A01. It uses the same mounting interface and wiring logic, allowing for a drop-in replacement in existing HVAC control loops.

What is the power requirement for this actuator?
The unit runs on 24 VAC. While the running consumption is approximately 3.3 VA, it is recommended to size your transformer for 10 VA per actuator to handle peak inrush and ensure stable operation.

Can this actuator be used on both 2-way and 3-way valves?
The SmartX M312A01 actuator is designed to fit all Schneider Electric VBB and VBS series valve bodies, including both two-way and three-way configurations, providing extreme versatility for various terminal unit applications.
