High-quality dual-run motor capacitor designed for reliable operation in residential and light commercial HVAC systems. Combines the compressor (HERM) and condenser fan circuits into a single unit for simpler installation and fewer failure points.
Key Features
- Dual capacitance: 45 MFD (compressor) + 7.5 MFD (fan)
- Dual voltage rating: 370/440 VAC (fully compatible with both 370 V and 440 V systems)
- Round aluminum case for excellent heat dissipation and durability
- Thick 7-micrometer metallized polypropylene film for superior reliability
- Vacuum-sealed construction to prevent leaks and contamination
- 1.5 mm plastic cup + Nomex sleeve for film roll support and insulation
- Industry-best ±3% tolerance (EIA-456-A)
- 10,000 AFC protected
- UL/CSA/VDE recognized
- 60,000-hour rated life at operating temperature
Benefits
- Drop-in replacement for most 45/7.5 MFD round dual run capacitors
- Reduces callbacks with tight tolerance and robust construction
- Handles higher voltage systems while remaining backward-compatible with 370 V units
- Long service life minimizes repeat service calls
- Single component powers both compressor and outdoor fan motor

Compatibility
Direct replacement for most HVAC systems requiring a 45/7.5 MFD round dual run capacitor at 370 or 440 VAC. Commonly used in split-system air conditioners and heat pumps for both the compressor and condenser fan motor.
Compatible with (or replaces) many equivalent part numbers such as:
- CAP-45/7.5/440R (Hartland)
- C34575R / C44575R
- Various GE/Genteq, Mars, Titan, Packard, and other 45+7.5 MFD 440 V round dual run capacitors
Note: Always match capacitance (MFD) exactly. Voltage rating may be equal or higher (440 V can replace 370 V), but never lower. Confirm terminal configuration and physical dimensions before installation.
Prop 65 Warning: This product contains chemicals known to the State of California to cause cancer.
Ideal for contractors and DIY technicians looking for a dependable, OEM-quality dual run capacitor with proven longevity and tight tolerances.
