The Schneider Electric / Barber Colman MA-418-0-0-4 is a 120V AC two-position spring-return electric actuator designed for reliable fail-safe control of commercial HVAC dampers and valves. Delivering 60 lb-in of output torque and a 180° clockwise rotation, this direct-coupled rotary actuator automatically returns to its default position upon power interruption to ensure critical building safety. Engineered with a durable NEMA 1 enclosure, the MA-418-0-0-4 provides long-lasting on/off actuation across air-handling units, ventilation systems, and hydronic loops.
