Schneider Electric (Erie) 0453H0077GA01 Actuator

The Schneider Electric (Erie) 0453H0077GA01 Actuator is a medium-duty damper actuator engineered for reliable two-position (on/off) airflow control in forced air zoning and draft control systems. Operating on 24Vac, this CW rotation motor utilizes a direct drive system to eliminate complex linkage adjustments during field installation. A key feature for contractors is the integrated end switch (SPDT), which provides essential feedback or auxiliary equipment sequencing. Built with a spring return mechanism, the 0453H0077GA01 ensures a fail-safe position upon power loss. The 55 in-oz torque rating is ideal for standard residential and light commercial dampers, providing enough force to overcome static pressure without over-stressing the gear train. The hysteresis synchronous motor includes a "lost motion" drive that protects internal gears from closing shock, significantly improving the service life of the Erie 453 series assembly in high-cycle applications.

• Fail-Safe Operation: Mechanical spring return ensures the damper returns to its original position during power outages.
• Integrated End Switch: Built-in SPDT end switch allows for simplified wiring of blowers, boilers, or staged equipment.
• Simplified Installation: Direct drive mounting for 5/16" shafts reduces labor time and eliminates linkage maintenance points.
• Gear Train Protection: Lost motion drive protects the synchronous motor from mechanical shock at the end of travel.
• Versatile Application: Optimized for medium duty performance in ambient environments ranging from 0°F to 120°F.

• Can this actuator replace a light-duty or 120V model? No, ensure your control circuit is 24Vac. This medium-duty 453H model provides 55 in-oz of torque, which handles larger dampers than the light-duty (453L) versions.
• Does this unit support counter-clockwise rotation? The 0453H0077GA01 is a dedicated clockwise (CW) rotation unit. Verify your damper shaft rotation requirements before installation.
• What gauge wire is recommended for the 18-inch leads? Standard 18 AWG field wiring is typically sufficient for these 10 VA rated 24V actuators in zoning applications.
