Description
Schneider Electric (Erie) AT33A000 Motor Actuator Overview
The Schneider Electric (Erie) AT33A000 is a reliable, commercial-grade motor actuator engineered for precise valve and damper positioning in HVAC systems. Operating on a 24Vac power supply, this actuator utilizes a three-wire floating control signal for accurate, responsive modulation — making it an ideal fit for hydronic zone valve and damper control applications where dependable performance is essential.
Key Features
- 24Vac operating voltage for compatibility with standard commercial HVAC control systems
- Three-wire floating signal input for smooth, proportional positioning control
- Non-spring return design — actuator holds its last position on power loss
- No time-out function, allowing unrestricted positioning without automatic reset
- Compact, durable motor actuator construction suited for demanding HVAC environments
- Designed for use with Erie valve and damper assemblies
Application
The AT33A000 is well-suited for commercial building automation, hydronic heating and cooling systems, and zone control applications. Its three-wire floating signal interface integrates seamlessly with a wide range of building automation system (BAS) controllers and DDC systems. The non-spring return configuration is ideal for applications where actuator position retention on power interruption is preferred over fail-safe return.
