Schneider Electric (Barber Colman) 2374-401 Relay Freon Automatic Reset Functionality: Restores circuitThe Schneider Electric 2374 401 Air Motion Relay, formerly under the Barber Colman brand, is a critical pneumatic component engineered for precise HVAC air pressure sensing and airflow monitoring. Designed to function as a differential pressure switch, this device triggers a pneumatic signal based on the presence or absence of air velocity. It operates with a minimum 0. 15" W. C. setpoint, making it sensitive enough to detect subtle changes in suction
