The S series NEMA 7 rotary electric actuator was designed solely for applications within the 200 lb × in (model SR) and 300 lb × in (model SX) torque range used in hazardous locations. These heavy-duty reversing actuators are used in place of model SD, SR, SDX and SX when the area used in requires enclosure rating of Class I Groups C & D or Class II Groups E, F & G div. I and II. These compact actuators are equipped with spur gear drive and as in all ICI actuators can with stand stall conditions without suffering gear failure. The heavy-duty sand-cast aluminum enclosure meets NEMA 7 specifications and has a thermally bonded ultraviolet resistant polyester powder coating that not only enhances its appearance but also is a tough corrosion resistant coating
Standard equipment includes 115Vac-1ph motor with thermal over load protection, two limit switches wired for light indication, stainless steel fasteners, 300 series stainless steel output drive and spring friction brake.
