Product Details

Belimo Damper Actuator

The Belimo damper actuator has an open/close control type. This actuator has an adjustable U-clamp, which accepts round or square shafts. It is a rotary/louver actuator. It is compatible with all the leading makes of HVAC controls. The damper actuator is fitted with a universal spindle clamp for quick and easy mounting directly on the damper spindle. The actuator is supplied with an ant rotation strap for fixing it at a position. This actuator operates on stall torque technology, which does not require end switches. The damper actuator has no limit switches and is overload proof. It requires a 240VAC/VDC supply voltage.

Optional auxiliary switch (stock no. 504-1545) suitable for use with LM, NM, SM, and GM damper actuators, features 2xSPDT switches rated at 3 (0.5)A 250Vac and supplied with 1m of cable.
