Siemens Industrial Controls 3UB81234EW2 Relay 326058-758 3-Pole Switching: Simultaneously controls all

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

this dual-terminal SPST pressure switch functions as a normally open control that proves the draft inducer motor is moving sufficient combustion air through the heat exchanger

you must verify the specific temperature rating and mounting bracket style required by the unit's data plate

Siemens Industrial Controls 3UB81234EW2 Relay 326058-758 3-Pole Switching: Simultaneously controls allThe 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
