ClimateMaster 13B0002N01 Contactor

The ClimateMaster 13B0002N01 Contactor is a heavy-duty 2-pole definite purpose contactor engineered for high-demand HVACR applications. Built to manage the electrical switching of compressors and fan motors in water source heat pumps and air conditioning systems, this 40 amp contactor features a 24V control coil. The dual-pole design ensures a complete break on both sides of the line, enhancing safety and reducing the risk of component degradation during high-draw startup cycles. With a compact open-frame construction and universal mounting bracket, it serves as a direct OEM replacement contactor for various ClimateMaster units, ensuring precise fitment and electrical compatibility for 50/60Hz operations. The silver cadmium oxide contacts are designed to resist pitting and welding, maintaining low contact resistance and stable conductivity across the HVAC electrical circuit throughout extensive mechanical cycles.

• Enhanced Load Management: Rated for a 40A inductive load, making it ideal for 3.5 to 5-ton heat pump compressors.
• Reduced Maintenance Callbacks: High-performance coil allows for quiet, chatter-free operation and prevents premature contactor failure.
• Broad Compatibility: Genuine ClimateMaster HVAC part designed for seamless integration with existing low-voltage thermostat control circuits.
• Durable Construction: Heavy-duty terminal lugs and 1/4" quick-connects provide secure, high-torque electrical connections.

• Can I use this to replace a 30 amp contactor? Yes, you can typically upgrade to a higher amperage rating like this 40A model, provided the coil voltage and pole count match the original HVAC contactor specifications.
• What causes a humming or buzzing noise? In many cases, a buzzing contactor indicates low voltage at the 24V coil or debris between the contact points, which can lead to pitted contacts if not addressed.
• Is this compatible with A2L refrigerants? This definite purpose contactor is designed for standard electrical switching and is compatible with modern equipment utilizing A2L or R-410A refrigerants.
