Siemens Industrial Controls 3RT2027-1AC20 Contactor 320788-704 Enhanced Safety Logic: Reliable SPST

Enhanced Safety Logic: Reliable SPST switching prevents ignition if the draft inducer or venting system is obstructed

which is the standard size for most residential condenser fan motors

designed to accurately monitor internal temperatures and interrupt electrical continuity to the heating element or motor if a threshold limit is exceeded

This motor is most commonly utilized as a draft inducer motor or flue exhaust blower motor in residential and light commercial furnaces

this 1/20 HP shaded pole motor operates at 3300 RPM to establish the necessary static pressure for the furnace pressure switch to prove the combustion cycle
