Siemens Combustion SQN71.603R19 Actuator
The Siemens Combustion SQN71.603R19 Actuator is a precision-engineered 120Vac reversing actuator designed for the reliable positioning of air and gas dampers in burner applications. This electromotoric actuator features a high-performance synchronous motor that drives a shaft and switch cam drum, providing exceptional control for two-stage or three-stage systems. With a running time of 25 seconds for 90° rotation at 60 Hz and a rated torque of 22 lb-in, the SQN71.603R19 ensures stability and accuracy in demanding combustion environments. The clockwise-rotating shaft can be manually disengaged via a clutch for simplified commissioning and adjustment. Built to technical specifications that meet UL and CSA certification standards, this Siemens damper motor integrates seamlessly into flame safeguard controls and HVACR systems, utilizing line voltage floating or proportional control to optimize burner efficiency.
Key Benefits:- Precision Control: Features two limit end switches and one auxiliary switch that are independently adjustable up to a 160° range.
- Contractor Friendly: The shaft disengagement clutch allowing for manual rotation significantly reduces time during field setup.
- Durable Construction: Engineered with an 80mm housing and a synchronous motor capable of maintaining a 11.5 lb-in holding torque.
- Universal Compatibility: Designed for diverse applications requiring rotary motion, including butterfly valves and flow control valves.
- What is the direction of rotation? This specific model is configured for clockwise (CW) rotation when facing the driveshaft.
- Can I add a potentiometer for feedback? Yes, the housing is designed to be indirectly suited for fitting a single- or double-position feedback potentiometer.
- Is this rated for outdoor use? It is rated for operating temperatures between -5° and 140° F, but should be protected from direct weather exposure according to Siemens installation standards.
