Belimo · Motors & Motion

Description  The Belimo GMB24-3 is a non fail-safe damper actuator designed to deliver reliable on/off and floating point control in HVAC air-handling applications. It provides 360 in-lb (40 Nm) of torque from an AC/DC 24 V power supply for accurate positioning of medium to large dampers.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category Actuators & Dampers Part Number GMB24-3 Subcategory Damper Actuators Actuator Type Non fail-safe Nominal Torque 360 in-lb (40 Nm) Nominal Voltage AC/DC 24 V Nominal Frequency 50/60 Hz Voltage Range AC 19.2…28.8 V / DC 21.6…28.8 V Power Consumption (Running) 4 W Power Consumption (Rest) 2 W Transformer Sizing 6 VA Control Type On/Off, Floating Point Angle of Rotation Max. 95°, adjustable Running Time 150 s / 90° Noise Level 45 dB(A) Manual Override External push button Electrical Connection 18 AWG plenum cable with 1/2" NPT conduit Degree of Protection IP54 / NEMA 2 Ambient Temperature -22…122°F (-30…50°C) Weight 4.6 lb (2.1 kg)   Information About  GMB24-3 The GMB24-3 is part of Belimo’s proven damper actuator portfolio developed for dependable airflow control in commercial HVAC systems. It is engineered with electronic overload protection across the full stroke to prevent actuator damage under stall or obstruction conditions. The actuator supports simple two-position and floating point control strategies, making it suitable for a wide range of air-handling and zoning applications. Designed for maintenance-free operation, it combines low power consumption with consistent torque output throughout its service life. Key Features High Torque Output For Dampers: Provides 360 in-lb (40 Nm) of torque to reliably drive medium and large HVAC dampers. Non Fail-Safe Operation: Maintains the last commanded damper position during power loss for predictable airflow control. Dual Control Capability: Supports both on/off and floating point control modes to match common HVAC control sequences. Electronic Overload Protection: Protects the actuator across the full 0…95° rotation range to enhance durability and operational safety. Adjustable Stroke Limitation: Mechanical end stops allow precise adjustment of the rotation angle to suit damper geometry. Manual Override Function: External push-button override enables manual positioning during commissioning or maintenance. Quiet And Efficient Performance: Low operating noise and reduced power consumption support use in occupied building spaces. The GMB24-3 delivers the reliability and precision required for dependable damper control in commercial HVAC air distribution systems.
