Siemens Industrial Controls 3UB81234EW2 Relay 326058-758 The Johnson Controls P74FA-10 is

The Johnson Controls P74FA-10 is a high-performance differential pressure control engineered for precision monitoring in commercial HVACR systems

Key Benefits for Technicians Broad Compatibility: Serves as the functional successor to the 510-312-254 model

making it suitable for a broad spectrum of duct static pressure and differential air pressure applications

3-Pole Switching: Simultaneously controls all three power legs to ensure balanced load distribution and motor protection

This 5 cell heat exchanger is engineered with precision to facilitate maximum thermal transfer while ensuring combustion gases remain isolated from the circulating air

Siemens Industrial Controls 3UB81234EW2 Relay 326058-758 The Johnson Controls P74FA-10 isThe Siemens 3UB81234EW2 is a high performance ESP200 solid state overload relay designed for precise motor protection in industrial HVACR and pumping applications. Engineered to replace legacy ESP100 units without enclosure modifications, this 3 phase overload relay handles a wide current range of 10 to 40 Amps. Unlike standard bimetallic options, the solid state design is ambient insensitive, virtually eliminating nuisance tripping caused by varying
