MS4104F1010 : Honeywell Damper Actuator Spring Return, Fast-Acting, Two-Position, 30 in-lb (3.4 Nm), 120 VAC, for Fire and Smoke Dampers

Honeywell Damper Actuator, Spring Return , Fast-Acting , Two-Position, 30 lb-in (3.4 Nm), 120 Vac, for Fire and Smoke Dampers. These Fast-Acting, Two-Position Actuators are line volt (120V), 30 lb-in., spring return direct coupled actuators (DCA) for Fire and Smoke dampers (on/off control). The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise (ccw) spring rotation.

Features:
30 lb-in. (3.4 N•m) minimum driving torque at 350 F (176 C)
Reversible mounting facilitates use in either clockwise (cw) or counterclockwise (ccw) spring rotation
Integral spring return ensures level of return torque
