The MS8309F is a 80 lb-in (9Nm), spring return direct-coupled, 24 Vac, CCW actuator that accepts two position (SPST) control
with an integral junction box. The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. They are designed to operate reliably in smoke control systems requiring Underwriter's Laboratories Inc. UL555S ratings up to 350 F.
•Integral spring return ensures level of return torque
•Fifteen-second spring return timing
•No special cycling required during long-term holding
•No audible noise during holding
•Patent pending design eliminates need for limit switches to reduce power consumption
•Models available for 24, 120, and 230 Vac
•Ninety-five degree angle of rotation for tight damper closure
•Actuator holds rated torque at reduced power level
•Die-cast aluminum housing
•Housing design allows flush mounting to damper
•Integral junction box with three conduit openings eliminates need for separate wiring box
Compatible Damper Shafts: 3/8 to 1/2 in. square or round (10 to 13 mm square/round)
Shaft Adapter Type: Aluminum Hub, four set screws Materials: Aluminum housing
Operating Humidity Range (% RH): 5 to 95% RH, non-condensing Ambient Temperature Range: 0 F to +130 F (-18 C to +55 C) Storage Temperature Range: -40 F to 140 F (-40 C to +60 C)
Weight: 6 lb (2.72 kg)
Comments: Integral junction box with three 7/8 in. conduit openings (fittings not included)
