Belimo LRB24-3 Non-Spring Return Damper Actuator - 24V

The Belimo LRB24-3 is a 24-volt electronic damper actuator designed for on/off or floating control applications in HVAC systems. This non-spring return actuator provides reliable positioning control for dampers in air handling systems, VAV boxes, and zone control applications.

Key Features:

• 24 VAC/DC power supply for flexible installation
• Non-spring return operation maintains damper position during power loss
• Floating control with on/off positioning capability
• 90-degree rotation for standard damper control
• 35 in-lb (4 Nm) torque output for positive damper control
• Integrated auxiliary switch for position indication or interlock functions
• Manual override for service and testing
• Compact, durable housing for long-term reliability

This actuator serves as a direct replacement for legacy Belimo models LR24-US, LR24-3, and LR24-1, providing an easy upgrade path while maintaining compatibility with existing control systems. The LRB24-3 meets industry standards for HVAC control applications and is suitable for both new installations and retrofit projects.
