Schneider Electric (Erie) 0453L0038GA00 Actuator

The Schneider Electric (Erie) 0453L0038GA00 Actuator is a 24V light duty spring return damper actuator designed for reliable control in multi-zone HVAC applications and solid fuel boiler draft systems. This two-position damper actuator utilizes a motor-driven linkage drive providing clockwise (CW) rotation and a normally closed (NC) position via spring return. With a 45 in-oz torque rating, it is engineered for precision in low-pressure forced air zoning. A critical technical advantage is the exclusive lost-motion drive, which decoupling the gear train from the output shaft at the end of the stroke to prevent mechanical binding and gear stripping. This genuine OEM 0453L0038GA00 ensures drop-in compatibility for technicians servicing Erie PopTop or similar light-duty assemblies. The unit features 2-wire thermostat control and includes an integrated SPDT auxiliary switch for status feedback or interlocking equipment, maintaining operational efficiency in temperatures ranging from 0°F to 120°F.

Technical Benefits

• Enhanced Gear Protection: The lost-motion drive mechanism shields the internal gear train from damage due to mechanical stops or damper resistance.
• Universal HVAC Integration: Operating on standard 24VAC 50/60 Hz power, it integrates seamlessly with most building automation and residential zoning controllers.
• Efficient Field Installation: Compact design with 18-inch leads and a quick-mounting linkage system reduces onsite labor time for contractors.
• Reliable Fail-Safe: Professional-grade spring return functionality ensures the damper returns to its normally closed position immediately upon power loss.

Common Questions

Is the 0453L0038GA00 compatible with residential zoning boards?
Yes, this 24V light duty spring return actuator is compatible with most 2-wire 24V HVAC zoning systems that require a clockwise opening rotation and a fail-safe closed position.

What is the purpose of the built-in auxiliary switch?
The integrated SPDT auxiliary switch allows for secondary equipment control, such as signaling a fan to start or a boiler to fire once the actuator has reached its position.

Can this actuator be used in high-static pressure commercial ducts?
This is a light-duty damper actuator with a 45 in-oz torque rating. It is designed specifically for residential zoning and low-pressure draft control; check your damper's torque requirements for high-pressure applications.
