Belimo LMB24-3-P5-T Motor Actuator

The Belimo LMB24-3-P5-T is a high-torque rotary actuator designed for precise control in HVAC applications. Engineered for damper control and butterfly valve automation, this unit provides 45 in-lb (5 Nm) torque, ensuring reliable operation of air dampers and water valves in complex 24VAC/DC circuits. Its versatile 3-point floating or on/off control logic allows for seamless integration into various building automation systems. This model features a direct-coupled mounting system with a universal clamp, reducing installation time for contractors in the field. Built with a brushless DC motor technology, the LMB24-3-P5-T offers constant torque over its entire 0 to 95-degree rotation range. The inclusion of a plenum-rated cable and its manual override functionality makes it a standard for HVAC zone control and VAV box maintenance. Rely on this Belimo actuator for thermal stability and low power consumption in demanding commercial environments.
