ClimateMaster 13B0002N02 Contactor

For service professionals maintaining ClimateMaster water-source heat pumps or residential condenser units, the ClimateMaster 13B0002N02 Contactor provides the high-amperage switching necessary for dependable compressor and fan motor operation. This 2-pole HVAC contactor is engineered as a 40 amp definite purpose contactor with a 24V coil, field-tested to handle the rigorous inrush currents of heavy-duty cooling equipment. Featuring heavy-duty silver cadmium oxide contacts, this OEM ClimateMaster replacement part minimizes pitting and oxidation, which are common causes of voltage drops and premature component failure in the field. The compact design ensures a proper fit in restricted control boxes, while the 24V 40A contactor ratings meet strict 50/60 Hz requirements for versatile application across various geothermal and air-source models. When diagnosing a system that hums but fails to engage the compressor, replacing a pitted or welded switch with this ClimateMaster 13B0002N02 restores mechanical reliability and stable electrical through-put to the high-voltage circuit.

• High-Conductivity Contacts: Utilizes silver-plated contact surfaces to maintain low resistance and prevent overheating during high-cycle operations.
• Universal Compatibility: Designed specifically for ClimateMaster units but serves as a robust 40 amp 2 pole contactor for any system requiring a 24V control circuit.
• Industrial-Grade Build: Features a definite purpose design with a reinforced class B insulation system to withstand high ambient temperatures within the electrical cabinet.
• Quick Installation: Equipped with standard male quick-connect terminals and #6-32 screw terminals for efficient wiring in the field.

• Can I use this to replace a 30 amp contactor? Yes. An amperage rating is a maximum capacity; a 40A contactor can safely replace a 30A version as long as the 2-pole configuration and 24V coil voltage match.
• Why is my contactor buzzing or chattering? Buzzing often indicates a weak 24V signal or debris in the magnetic armature. If the coil resistance is out of spec or the contacts are pitted, a full replacement of the 13B0002N02 is recommended.
• Is this suitable for 50Hz or 60Hz systems? This OEM part is rated for both 50Hz and 60Hz applications, making it ideal for standard North American and export geothermal equipment.
