Actuator: Damper, On/Off, Spring Return, 35 in-lb, 120V AC, Hardwired, NEMA 2 / IP54.

Fail-safe actuators control connected dampers while ensuring they function safely in an emergency. They use a motor to move the connected damper and feature a spring-return mechanism to move them to a safe position in the event of a power loss. They are recommended for critical infrastructure components that must remain open or closed during an emergency.
