Lennox 74H01 Potential Relay 318518-761 and FAN2712KThe 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
