Compatibility
Direct replacement for many OEM and aftermarket 35/3 MFD dual run capacitors used in air conditioners, heat pumps, packaged units/RTUs, and air handlers. Commonly replaces equivalent Hartland Controls / Littelfuse CAP-35/3/440R and other TradePro or competitive dual run capacitors with matching microfarad and voltage ratings. Always confirm exact microfarad values, voltage, physical dimensions, and terminal configuration against the existing capacitor and equipment nameplate before installation.
Note: Proper discharge and safe handling procedures are required when replacing capacitors. Professional installation is recommended.
Key features
- Dual Run Capacitor — 35 + 3 MFD for compressor and fan
- 370/440 VAC Rated — works in either application
- Round Aluminum Can — fits standard mounting brackets
- TradePro OEM-Quality — for residential and light commercial systems
