Belimo 24V ac/dc Open/Close Damper Actuator 40Nm IP54 Rotary/Louver HVAC Control GM24A

Belimo GM24A is a 24V ac/dc open/close Damper Actuator with 40Nm motor torque, engineered for precise control of air dampers in ventilation and HVAC systems. This rotary/louver actuator supports damper spindle sizes between 12mm and 26.7mm, covering a maximum damper area of up to 8 square meters. It operates using stall torque technology, eliminating the need for end switches and is overload-proof, ensuring reliable and maintenance-free performance.

The actuator features a noise emission of 45dBA and runs a full 95° rotation in approximately 150 seconds. It is rated IP54 for protection against dust and moisture, suitable for ambient operating temperatures from -30°C up to 50°C. An adjustable U-clamp accepts both round and square shafts, and a pushbutton manual override provides easy manual control.

Additional benefits include a minimum rated life of 60,000 operations, low power consumption at 4W, and compliance with multiple international standards including RoHS, EN, CE, and UL. The device is designed for applications in industrial and commercial HVAC systems for efficient air flow management.

An optional auxiliary switch (stock no. 504-1545) is available for enhanced functionality, compatible with LM, NM, SM, and GM actuator ranges featuring dual SPDT switches rated at 3 (0.5)A 250Vac with a 1m cable length.

The actuator operates at 24V ac/dc voltage with a power consumption of 4W. It offers a motor torque of 40Nm suitable for heavy-duty damper actuation. IP54 enclosure protects internal components from dust and water ingress.

The device supports damper spindle sizes from 12 to 26.7mm with a maximum damper area capacity of 8m². Running time for full rotation is 150 seconds with a 95° angle of rotation. Operational temperature range is -30°C to 50°C ensuring versatility in harsh environments.

Designed for open/close control, ideal for ventilation and air conditioning systems. Maintenance-free with a minimum operation life of 60,000 cycles. The actuator includes a pushbutton manual override and direction change switch for flexible operation.

Complies with RoHS, EN, CE, UL, and IEC/EN certifications validating quality standards.
