Bard 8401-038BX 2-Pole 40A Contactor with Auxiliary Switch 24V OEM HVAC Replacement

The Bard 8401-038BX is a genuine OEM 2-pole contactor with auxiliary switch, rated at 40 amps with a 24V control coil, designed for use in Bard wall-mount HVAC systems. As an electrically operated switching device, it controls the flow of high-voltage power to key system loads on a call from the thermostat or control board.

Key Features:

• 2-Pole configuration for single-phase power switching
• 40A current rating for high-load compressor and fan motor applications
• 24V coil voltage for direct integration with standard low-voltage HVAC control circuits
• Integrated auxiliary switch for additional circuit control within the system
• Genuine OEM Bard replacement part — boxed packaging (BX suffix)
• Engineered for reliable, high-cycle operation in demanding HVAC environments

This contactor switches power to critical system components including the compressor, condenser fan motor, and heating elements. The onboard auxiliary contact provides expanded control flexibility for secondary circuits. Common symptoms of a failing contactor include system chattering, failure to start on a cooling or heating call, intermittent cycling, or visibly burned contact points. Replacing with this genuine OEM part restores correct electrical operation and protects downstream components.
