Siemens Building Technology GCA226.1U Actuator
The Siemens GCA226.1U is a heavy-duty OpenAir electronic damper actuator engineered for precise two-position control in commercial HVAC systems. Operating on a 120V AC power supply, this spring return actuator delivers a robust 160 lb-in torque (18 Nm), making it the professional choice for managing large dampers in air handling units, mixed air sections, and exhaust systems. The integrated dual auxiliary switches provide critical end-stop feedback or interlocking capabilities for fans and peripheral equipment, ensuring seamless integration into complex building automation sequences.
Built with a rugged die-cast aluminum housing and a brushless DC motor, the GCA226.1U features stall protection to prevent motor burnout during unexpected obstructions. The patented self-centering shaft coupling accommodates various shaft sizes, significantly reducing installation time and ensuring a secure mechanical connection. In the event of a power loss, the mechanical fail-safe returns the damper to its original position within 15 seconds, protecting the coil and maintaining system integrity. This direct-coupled actuator is rated NEMA 2 (IP54) and comes pre-cabled with a 3-foot lead for straightforward field wiring.
Key Benefits- Fail-Safe Reliability: High-performance clockwise or counter-clockwise spring return ensures dampers close or open securely during power interruptions.
- Advanced Positioning: Features a visible position indicator and manual override for easy mechanical commissioning and troubleshooting.
- Durable Construction: All-metal housing protects internal gears and silicone-free lubrication ensures long-term operation in demanding environments.
- Versatile Mounting: Fits round shafts up to 1" and square shafts up to 3/4", eliminating the need for complex mounting brackets.
- Efficient Power Management: Low power consumption of 8 VA while running and only 6 VA in holding mode.
What is the maximum damper area this 160 lb-in actuator can handle?
Typically, the GCA226.1U is rated for dampers up to 40 square feet, though this varies based on seal types and system static pressure.
Can the auxiliary switches be adjusted in the field?
Yes, the dual auxiliary switches are fully adjustable between 0° and 90° for precise signaling at any point in the rotation.
Is this model suitable for outdoor installations?
The unit is rated NEMA 2; however, for full weather protection and NEMA 3R compliance, it should be installed with an ASK75.1U weather shield.
