This heavy-duty 208V to 24V HVAC transformer is specifically engineered to step down 208V primary line voltage to a reliable 24V secondary output

9 cubic inches per revolution and utilizes Polyolester (POE) oil to ensure consistent lubrication and internal component longevity

Its robust diaphragm design handles back-pressure fluctuations

or if you encounter persistent "Communication Loss" alarms that are not resolved by checking the ribbon cables

Lennox 74H01 Potential Relay 30067439-890 This heavy-duty 208V to 24VThe Lennox 74H01 Potential Relay is a mission critical OEM replacement part designed for high torque motor starting applications in residential heating and commercial air conditioning systems. Engineered to manage compressor start up cycles, this potential type motor starting relay features a normally closed (SP N. C.) contact configuration that effectively removes the start capacitor from the circuit once the motor reaches sufficient back
