Schneider Electric (Erie) 0453H0077GB01 Actuator

The Schneider Electric (Erie) 0453H0077GB01 Actuator is a reliable 120Vac damper actuator engineered for medium-duty commercial and industrial zone control. This two-position damper actuator features a robust spring return mechanism, ensuring fail-safe positioning during power loss. With a 55 in-oz torque rating and a direct drive interface, this unit provides precise control over airflow in HVAC systems without the complexity of external linkages. The integrated SPDT end switch allows for seamless sequence of operation signaling, making it an essential component for interlocking with fans or auxiliary equipment.

Designed for clockwise (CW) rotation, this H-Series actuator utilizes a hysteresis synchronous motor with a lost motion drive. This technical design protects the internal gear train from closing shocks, significantly extending the service life in high-cycle applications. The NEMA 1 rated housing and 18-inch appliance leads simplify installation in tight mechanical spaces, while the 0°F to 120°F operating range ensures stability across various plenum conditions.

• Fail-Safe Reliability: The mechanical spring return ensures dampers return to their original position during power interruptions.
• Enhanced Control: Built-in SPDT auxiliary switch provides feedback or control over secondary HVAC components.
• Gear Train Protection: Lost motion drive technology absorbs impact, reducing wear on the synchronous motor.
• Direct Mounting: Simplified direct drive setup eliminates the need for expensive linkage kits.
• Industrial Build: Medium-duty construction rated for 55 in-oz torque, ideal for multi-zone damper assemblies.

What is the primary application for the 0453H0077GB01?
This actuator is specifically designed for two-position (on/off) control of air dampers in medium-duty HVAC applications where a 120V power supply is required.

Does this model include a feedback switch?
Yes, the 0453H0077GB01 comes standard with an internal end switch to verify the actuator’s position or trigger auxiliary devices.

Can I install this on a counter-clockwise (CCW) damper?
This specific model is a clockwise (CW) rotation unit. Ensure your damper shaft and fail-safe requirements align with CW rotation before installation.
