Compatibility
Direct replacement for most 45 MFD round single run capacitors rated 370 V or 440 V in air conditioners, heat pumps, condenser units, and similar HVAC equipment. Compatible with systems that originally used equivalent TRADEPRO, Hartland Controls/Littelfuse (e.g., CAP-45/440R or HCKS450R440 series), and other OEM/aftermarket 45 µF single run capacitors of matching voltage, shape, and approximate dimensions.
Note: Always verify the original microfarad rating, voltage, physical size, and terminal configuration before replacement. A 440 V can safely replace a 370 V unit of the same capacitance, but the reverse is not recommended. Proper discharge and safe handling procedures should be followed during installation.
Key features
- Single Run Capacitor — 45 MFD rating
- 370/440 VAC Rated — works in either application
- Round Aluminum Can — fits standard mounting brackets
- Reliable Motor Operation — for compressors and fan motors
