Lennox 48G59 Contactor
The Lennox 48G59 Definite Purpose Contactor is a high-performance 2-Pole electrical relay engineered for demanding single-phase HVACR applications. Operating with a 24V AC coil, this 40 Amp contactor features a Double Pole Double Throw (DPDT) configuration, providing professional technicians with the versatility to control two separate circuits simultaneously. It is frequently employed in Lennox, Armstrong, and Ducane residential condensing units to manage high-current loads for compressors and outdoor fan motors. With a Locked Rotor Amp (LRA) rating of 240A at 240V and 50A resistive capacity, this component ensures reliable switching under heavy inductive loads. Designed for direct OEM replacement, the 48G59 minimizes installation time with standard spade terminals and a compact footprint. This industrial-grade contactor is UL/CUL listed and includes an auxiliary switch for additional control logic integration, maintaining system integrity in high-cycle environments.
Key Benefits- Dual Circuit Control: The DPDT configuration allows for independent management of multiple system components from a single 24V signal.
- High Amperage Rating: Rated for 40 FLA (Full Load Amps), providing robust power handling for high-tonnage AC units and heat pumps.
- Universal Compatibility: Replaces Lennox part number 48G5901 and is compatible with Allied, Concord, and Magic-Pak equipment.
- Enhanced Durability: Features heavy-duty silver cadmium oxide contacts to resist welding and pitting during high-inrush starts.
Can I use this 48G59 contactor to replace a single-pole unit?
While a 2-pole contactor breaks both legs of the power line for increased safety, you must ensure the 24V coil voltage and 40A rating match your specific equipment schematic before modification.
What causes a contactor coil to buzz or chatter?
Chattering is typically caused by low voltage to the coil (below 24V), a faulty thermostat, or debris between the armature and the magnet. Replacing a pitted or carbon-fouled contactor prevents compressor failure.
Is the auxiliary switch removable?
The integrated auxiliary switch is part of the Lennox 48G59 assembly, often used for interlocking or signaling auxiliary heat components in complex control circuits.
