Siemens SQM33.511A9 Actuator - 2.5 Nm Torque, 3-20s Adjustable Running Time, 220-240V AC for Air and Gas Dampers

The Siemens SQM33.511A9 is a robust and reliable rotary actuator, specifically designed for precise control of air dampers or gas valves in gas and oil burners of medium to high capacity. This compact electro-mechanical actuator delivers a powerful 2.5 Nm (Newton-meter) torque, ensuring effective and consistent adjustment of damper positions. A key feature is its adjustable running time from 3 to 20 seconds, allowing for flexible adaptation to various combustion process requirements and precise control over air or gas flow.

Operating on a 220-240V AC (Alternating Current) supply voltage at 50/60 Hz, the SQM33.511A9 is suitable for a wide array of international industrial and commercial applications. It functions as a crucial component in managing the combustion air supply or fuel gas flow to the burner, thereby optimizing combustion efficiency, ensuring safety, and regulating heat output. The actuator features robust mechanical limit switches for defining end positions and typically offers clear visual indication of its current position. Its durable construction is engineered for long-term, trouble-free operation in challenging industrial environments. Easy to install and commission, the Siemens SQM33.511A9 actuator is an essential component for modern burner management systems that prioritize energy efficiency, precise control, and operational reliability. This offering includes one (1) unit.
