Belimo LMCB24-3 Actuator Motor

The Belimo LMCB24-3 is a high-performance rotary actuator engineered for precise control in HVAC applications requiring 45 in-lb torque. Designed for versatile integration, this 24V actuator supports on/off and floating point control for dampers, valves, and air handlers. Its brushless DC motor technology ensures consistent timing and torque delivery throughout its service life, while the manual override button allows for quick field adjustments during commissioning. The LMCB24-3 features a standard universal clamp for effortless mounting to 5/16" to 5/8" shafts, making it a reliable choice for direct-coupled actuator replacements and new installations alike. With low power consumption during operation and a NEMA 2/IP54 rated housing, this unit maintains HVAC damper control integrity in demanding mechanical environments. Contractors trust the LMCB24-3 for its field-proven reliability and easy electrical connection via terminal strips.

• High Torque Efficiency: Delivers 45 in-lb of consistent torque suitable for medium-sized damper applications.
• Universal Compatibility: Operates on both 24VAC and 24VDC power supplies for flexible field wiring.
• Field Adjustability: Integrated manual override and adjustable angle of rotation (0 to 95 degrees) simplify installation.
• Durable Construction: NEMA 2 / IP54 rated enclosure provides protection against dust and moisture in mechanical rooms.
• Reduced Maintenance: Brushless DC motor eliminates the need for frequent calibration or motor brush replacement.

What is the typical runtime for the LMCB24-3?
The standard motor runtime is approximately 150 seconds, providing smooth and controlled movement for air regulation.

Can this actuator be used in variable air volume (VAV) systems?
Yes, the Belimo LMCB24-3 is frequently utilized in VAV boxes and small air handling units requiring floating point or on/off control signals.

What wire size is recommended for installation?
Standard 18 AWG plenum-rated cable is recommended; however, always refer to the local electrical code and the specific submittal sheet for long-distance runs to manage voltage drop.
