Belimo LRB24-3-S Rotary Damper Actuator 24V On/Off 45 in-lb

The Belimo LRB24-3-S is a 24-volt spring return rotary damper actuator designed for commercial HVAC applications requiring reliable on/off control. This non-spring return actuator delivers 45 in-lb of torque, making it suitable for modulating dampers in air handling systems, VAV boxes, and zone control applications.

Key Features:

• 24V AC/DC power supply for versatile installation
• 45 in-lb torque output for positive damper positioning
• On/Off control with floating signal capability
• Auxiliary switch for end position feedback
• Non-spring return (NSR) operation maintains position on power loss
• Compact rotary design for direct damper shaft mounting
• Durable construction for long service life in commercial environments

This actuator provides dependable damper control for heating, ventilation, and air conditioning systems. The auxiliary switch enables remote position monitoring, while the non-spring return design holds the damper in its last position during power interruptions. Ideal for building automation systems requiring precise airflow control.
