Siemens Building Technology GCA226.1U Actuator 324846-701 The control will naturally energize

The control will naturally energize when the liquid contacts the LLCO probe and de-energize when the level drops below it for more than three seconds

Optimized Airflow: The specialized internal curve minimizes static pressure and restrictions

this sequencer control board prevents excessive amperage draws on startup and ensures balanced thermal output throughout the heating cycle

Direct OEM Match: Eliminates the guesswork found with universal switches

HVAC-Modified Housing: The standard duty cast iron construction is optimized for the thermal and mechanical loads of commercial ventilation

Siemens Building Technology GCA226.1U Actuator 324846-701 The control will naturally energizeThe 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
