Climatemaster C13B0003N02 3-pole Contactor 40A 24V Coil

Product Description

The CLIMATEMASTER C13B0003N02 is a 3-pole contactor designed for electrically switched load control in HVAC systems. Rated at 40 amps with a 24-volt control coil, this contactor operates as a relay-style switching device that opens and closes high-current circuits on command from a low-voltage control signal. When the thermostat or control board energizes the 24-volt coil, the electromagnetic pull closes all three poles simultaneously, completing the power circuit to the load. Licensed HVAC technicians install and service these components as part of routine equipment maintenance and failure diagnosis.

This contactor is suited for residential and light commercial HVAC applications where a 3-pole, 40-amp switching device is required. Typical loads include compressors, condenser fan motors, and electric resistance heaters. The 24-volt coil voltage aligns with standard low-voltage control circuit configurations found in split systems, package units, and heat pumps. It is appropriate for any system where the original equipment calls for a 3-pole contactor at this amperage and coil voltage rating.

Key Features

• 3-pole configuration switches all three legs of a load circuit simultaneously
• 40-amp current rating handles high-draw HVAC loads including compressors and electric heaters
• 24-volt coil integrates with standard low-voltage thermostat control circuits
• Electrically controlled switching reduces mechanical wear compared to manual switching
• OEM-style replacement maintains original system control logic without rewiring

Compatibility

Designed as an OEM-style replacement contactor for HVAC systems requiring a 3-pole, 40-amp, 24-volt coil contactor. Verify the pole count, amperage rating, and coil voltage against the original equipment specifications before installation.

Installation Notes

Contactors are installed and replaced by licensed HVAC technicians. Disconnect and lock out all power to the unit before removing or installing this component. Confirm the coil voltage and amperage rating match the original part before making any connections. Follow applicable NEC requirements for high-voltage wiring terminations in HVAC equipment.
