Bard HVAC S8401-007 Contactor

The Bard HVAC S8401-007 Contactor is the direct OEM successor to the 8401-007, engineered specifically for switching high-voltage loads in Bard wall-mount and packaged units. As a 1-pole 25 amp contactor with a 24V coil, this component is frequently used to manage compressor and outdoor fan motor operations. For technicians troubleshooting chattering, pitted contacts, or a total failure to pull in under a 24VAC control circuit signal, this Bard replacement contactor provides a drop-in solution to restore equipment reliability. This single pole contactor features a compact footprint ideal for tight control boxes, while the 25-amp inductive rating ensures it handles the high inrush currents typical of standard HVACR startup cycles. When performing a contactor replacement, verify that the 24V HVAC contactor matches your system's wiring diagram to maintain intended safety and performance standards for Bard HVAC parts.

• Direct OEM Compatibility: Specifically designed as the factory-authorized update for the 8401-007, ensuring exact fit and terminal alignment in Bard equipment.
• Reliable Power Switching: Rated for 25 continuous amps to support the high-demand cycles of compressors and fan motors without premature contact welding.
• Standardized 24V Control: Integrates seamlessly with existing 24VAC thermostats and control boards, minimizing installation time for field technicians.
• Commercial-Grade Construction: Built to withstand the environmental stressors of wall-mount HVAC applications, reducing service callbacks for contact failure.

Is the S8401-007 a direct replacement for the 8401-007?
Yes, the S8401-007 is the official updated version provided by Bard to replace the older 8401-007 model without requiring cabinet or wiring modifications.

What are the signs that this 1-pole contactor needs to be replaced?
Common indicators include a humming/chattering sound during a call for cooling, visible carbon buildup or pitting on the contacts, or the compressor failing to start despite receiving a 24V signal at the coil.

Can this contactor be used in other 25A 24V applications?
While technically rated for 25A and 24V, it is best practice to use this part in Bard HVAC systems where the terminal configuration and mounting footprint are verified against the original equipment manufacturer's specifications.
