Climatemaster C13B0002N02 2-pole Contactor 40A 24V

Product Description

The CLIMATEMASTER C13B0002N02 is a 2-pole contactor rated at 40 amps and 24 volts, designed for use in HVAC systems where reliable high-current switching is required. A contactor is an electrically controlled switch that opens and closes the circuit to high-voltage loads such as compressors and condenser fan motors. The coil is energized by a 24-volt control signal from the thermostat or control board, which pulls in the contacts and allows line-voltage power to flow to the load. Compatible with both 50 Hz and 60 Hz systems, this unit suits most North American HVAC installations.

This contactor is intended for use in residential and light commercial heat pumps and air conditioning units where a 2-pole, 40-amp contactor is specified. It is installed in the condensing unit disconnect circuit and is typically serviced by a licensed HVAC technician during a compressor replacement, contactor replacement, or system commissioning. The 24-volt coil voltage is standard for low-voltage thermostat control wiring used throughout residential split-system equipment.

Key Features

• 2-pole design switches both legs of line voltage simultaneously for proper load isolation
• 40-amp current rating supports compressor and condenser fan motor loads
• 24-volt coil voltage compatible with standard low-voltage HVAC control circuits
• Rated for operation on both 50 Hz and 60 Hz power systems
• Silver contacts promote reliable electrical conductivity and long contact life

Compatibility

Designed as an OEM-style replacement contactor for heat pump and air conditioning condensing units requiring a 2-pole, 40-amp, 24-volt coil contactor.

Installation Notes

Contactor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit at the disconnect box before removing the existing contactor. Verify coil voltage and pole configuration match the existing unit before installation. Follow applicable NEC requirements for line-voltage wiring connections at the contactor terminals.
