Siemens GCA126.1U Damper Actuator

The Siemens GCA126.1U Damper Actuator is a precision direct-coupled, electronic 2-position damper actuator with spring-return, designed for HVAC dampers. It operates on 24 Volt AC/DC with 50/60 Hz, delivering reliable, fail-safe control for ventilation systems. This actuator combines robust torque, compact size, and durable construction to support a wide range of damper applications.

Key specs include 380 in-lb torque, a 95-degree rotation, and a die-cast aluminum alloy body housed in a NEMA 2 enclosure. Its compact footprint (4.75" W x 2.88" D x 12" H) and 3/4" shaft diameter make it easy to install in tight spaces, while a 3-foot 18 AWG supply cable simplifies wiring. Suitable for both Constant and Variable Air Volume installations, it excels in Return Air, Mixed Air, Exhaust, Face and Bypass Dampers, ensuring precise airflow control across environments.
