Schneider Electric (Erie) 0453H0077GA00 Actuator

For high-efficiency airflow control, the Schneider Electric (Erie) 0453H0077GA00 Actuator is a reliable, medium-duty solution designed for two-position damper applications. Engineering for direct-drive installation, this 24Vac spring return actuator provides 55 in-oz of torque, ensuring positive closure and consistent performance in commercial and residential HVAC systems. The hysteresis synchronous motor includes a integrated lost motion drive to protect the internal gear train from closing shock, extending the operational life of the unit during repeated cycles. This clockwise rotation actuator (CW) is primarily controlled via a simple two-wire thermostat connection, making it a drop-in replacement for many legacy Erie damper motor configurations including those requiring a 5/16-inch shaft engagement. With a NEMA 1 protection rating and 18-inch leads, this Erie 453H series actuator is optimized for technicians needing a rugged, fail-safe component for zone control dampening and ventilation management.

• Direct Drive Hardware: Mounts directly to 5/16-inch damper shafts with a maximum engagement of 7/8-inch, reducing installation time and mechanical complexity.
• Spring Return Reliability: Mechanical fail-safe ensures dampers return to their original position during power interruptions.
• Gear Train Protection: The "lost motion" drive mechanism absorbs shocks at the end of the stroke to prevent premature mechanical wear.
• Simple Integration: Standard 24V 50/60 Hz power requirements and two-wire control facilitate easy wiring into existing control loops.

Is the 0453H0077GA00 compatible with Trol-A-Temp systems?
Yes, this model is frequently used as a direct replacement for Trol-A-Temp RDMZ actuators, though you should verify the specific shaft size and clockwise rotation requirement for your application.

What is the maximum torque and rotation for this unit?
The unit provides 55 in-oz of torque and is configured for clockwise (CW) rotation. For counter-clockwise requirements, a different H-series model number is necessary.

Can this be used in high-moisture environments?
This actuator carries a NEMA 1 rating, meaning it is designed for indoor use and protected against falling dirt, but it is not intended for wet or non-condensing high-humidity conditions.
