Belimo TFB120 Damper Actuator

The Belimo TFB120 Damper Actuator is an ON/OFF damper actuator designed for direct-coupled, spring-return operation. It delivers reliable HVAC control across a range of applications.

This model runs on 100–240 VAC (50/60 Hz), consuming 2.5 W running and 1.3 W holding, with a torque of 22 in-lb and a 95° rotation. Its NEMA 2 / IP42 enclosure protects the actuator in typical HVAC environments, while a 1/4"–1/2" shaft fits common damper linkages. A 3 ft 18 AWG appliance cable with a 1/2" conduit connector simplifies field wiring.
