Siemens Building Technology GCA131.1U Actuator
The Siemens Building Technology GCA131.1U Actuator is a heavy-duty spring return rotary damper actuator designed for the digital or analog control of building HVAC dampers. Operating on 24VAC/DC, this OpenAir series component delivers 160 lb-in (18 Nm) of torque, making it suitable for larger air handling units, mixed air, and exhaust dampers. This model features 3-point floating control and a 90-second nominal runtime, ensuring precise positioning in constant volume (CAV) or variable air volume (VAV) systems. Built with brushless DC motor technology and integrated stall protection, the GCA131.1U provides consistent performance without the risk of burnout at end-of-stroke. The die-cast aluminum alloy housing is NEMA 2 rated, providing the ruggedness required for demanding mechanical rooms. For field convenience, it includes a patented self-centering shaft coupling that accommodates various shaft diameters and a manual override for testing and commissioning.
Key Benefits- Fail-Safe Reliability: Mechanical spring return ensures the damper returns to a safe position during power loss.
- High Torque Output: Provides 160 lb-in of force, capable of driving large dampers or multiple linked sections.
- Brushless DC Motor: Maintenance-free operation with electronic stall protection for increased longevity.
- Universal Compatibility: The self-centering shaft adapter accepts round shafts up to 1" and square shafts up to 3/4".
- Simplified Installation: Features 18 AWG precabled connections and a visible position indicator for fast setup.
Is the GCA131.1U compatible with 120V systems?
No, this specific model is designed for 24VAC or 24VDC power supplies. For 120V applications, a different model in the GCA series must be used.
What is the difference between the GCA131.1U and the GCA131.1P?
The "U" designation typically indicates an appliance cable for standard wiring, while the "P" version utilizes plenum-rated cable for use in air handling spaces without conduit.
Can I manually position the damper during a power outage?
Yes, the unit includes a manual override with a 3mm hex key and a locking mechanism to hold the damper in position during commissioning.
