Schneider MC-351 24VAC Actuator Non-Spring 2-Postion 220#

For two-position operation of dampers or valves in heating, ventilating and air-conditioning systems and similar applications where return to normal position is not required. These unidirectional actuators (clockwise rotation) require a three-wire control circuit; SPDT snap-acting switch or its equivalent such as a thermostat, pressure switch or relay. A built-in cam operated, snap-acting, adjustable SPDT auxiliary switch is standard. It is factory set to make at mid-stroke. One contact closes at end of stroke; other contact closes at end of next stroke.
