Description
Siemens GCA221.1U Electric Damper Actuator is a reliable spring return actuator for high performance in microprocessor controlled dampers of HVAC systems. The actuator is operated at 120 Vac and a torque of this amount to ensure robust performance and damper movement control. The includes a rugged die-cast aluminum alloy housing compliant with NEMA 2 standards and IP54 protection providing reliable operation in many indoor environments; the is compact but powerful, applicable to a broad range of HVAC applications. It is for different electrical systems because the actuator operates at a frequency of 50/60 Hz. Its spring return mechanism also guarantees that the damper returns to standard position in case of a power failure to increase safety and reliability.
