Bard 8552-079BX Capacitor

The Bard 8552-079BX Capacitor is a high-performance 45/10 MFD 370V dual run component designed for professional HVACR maintenance and repair. Engineered as a direct OEM replacement for the obsolete 8552-079, this round run capacitor provides the precise phase shift required for compressor and condenser fan motor operation in Bard wall-mounted air conditioners and heat pumps. With a capacitance rating of 45+10 microfarads, it manages the electrical loads of both the start and run cycles, ensuring high volumetric efficiency and reduced motor stress. The "BX" designation indicates a boxed unit, maintaining the same form and function as its unboxed counterparts. Operating at 370 VAC, this non-PCB, metallized polypropylene film capacitor is built to withstand demanding field conditions, helping technicians resolve common issues like hard starting, motor humming, or intermittent thermal overloads. Professional installation is recommended to ensure correct terminal wiring (Herm, Fan, and C) and proper electrical discharge.

• Dual-Run Versatility: Consolidates compressor (45 MFD) and fan (10 MFD) functions into a single round dual run capacitor for streamlined cabinet space.
• OEM Compatibility: Specifically designed for Bard wall-mount HVAC units, ensuring exact electrical matching and physical fit.
• Enhanced Motor Longevity: Provides stable capacitance to minimize energy wastage and prevent overheating in condenser fan motors.
• Internal Safety: Features a physical pressure interrupter to safely disconnect the capacitor in the event of an internal failure.

Can I use a 440V capacitor to replace this 370V model?
Yes, technicians often use 440V rated capacitors as they can handle higher voltage spikes while maintaining the same 45/10 MFD capacitance, but you should never undersize the voltage rating below 370V.

What does the "BX" suffix on the Bard 8552-079BX signify?
The "BX" suffix is used by Bard to indicate that the part is individually boxed for retail or shipping. It is physically and technically identical to the 8552-079 part number used in factory assembly.

How do I know if my 45/10 370V capacitor is failing?
Common signs include a visible bulge at the top of the canister, a motor that hums but fails to start, or a system that trips the breaker specifically during the compressor start-up cycle.
