Schneider Electric (Barber Colman) MF51-7103-100 Valve Actuator S/R Floating 105 In-lb W/Manual Override 24V

The Schneider Electric (Barber Colman) MF51-7103-100 is a 24-volt float switch used to control liquid levels in a wide range of HVAC systems. It guarantees dependable operation with its strong 105-pound load capacity and single-pole, double-throw (SPDT) arrangement. The mark "single reed," indicates that a single magnetic reed switch is used for consistent level detection. The float attached to the switch causes the reed to twitch, resulting in an electrical signal when liquid levels change. Pumps, valves, and alarms are then turned on or off by this signal, preserving equipment performance overflow. This adaptable float switch, which is widely used in HVAC systems including condensate drain pans, cooling towers, humidifiers, and dehumidifiers, simplifies liquid level management, improving effectiveness, lowering maintenance, and boosting safety by preventing overflow.
