Frequently Asked Questions
What is the Siemens SQN 30 111A3500 servomotor used for?
The Siemens SQN 30 111A3500 is a synchronous reversible servomotor designed for controlling air dampers and regulating valves on oil and gas burners of low to medium heating capacity. It is used in HVAC systems for load-dependent modulation of fuel and combustion air volumes, typically paired with controllers like the RWF40 or safety boxes such as the LMO series.
What are the specifications of the Siemens SQN 30 111A3500?
The Siemens SQN 30 111A3500 delivers 1 Nm nominal torque with a holding torque of 0.8 Nm. It operates at 50–60 Hz and is rated for 220 V~ −15% / 240 V~ +10% or 100 V~ −15% / 110 V~ +10%. Rotation time at 90° is 4.5 s. The motor is left-hand rotation and includes a robust plastic housing, screw terminals, and adjustable auxiliary and limit switches.
