Description
Product Description
The MARS tp-cap-40/5/440usar is a round dual run capacitor rated at 40/5 microfarads (MFD) and 440 volts, manufactured in the USA. Dual run capacitors serve two motor circuits in a single package, typically supporting both the compressor and the condenser fan motor in a split-system air conditioner or heat pump. This capacitor maintains the phase shift needed to start and run those motors efficiently, and it is a direct replacement part installed by licensed HVAC technicians during routine maintenance or compressor and fan motor replacement service.
This capacitor is suited for residential and light commercial HVAC applications where a round-style dual run capacitor rated 40/5 MFD at 440 volts is required. The 440-volt rating makes it compatible with both 370-volt and 440-volt systems, giving technicians flexibility when stocking replacement parts. It is commonly installed in split-system condensing units and packaged units that call for this capacitor rating.
Key Features
- Dual run capacitor supports compressor (40 MFD) and condenser fan motor (5 MFD) in one unit
- 440-volt rating compatible with both 370V and 440V HVAC systems
- Round form factor fits standard capacitor brackets and mounting straps
- USA manufactured construction
- Sold individually (each)
Compatibility
Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system condensing units and packaged HVAC equipment requiring a 40/5 MFD, 440-volt round capacitor.
Installation Notes
Dual run capacitors must be replaced by a qualified HVAC technician. Always disconnect and lock out power to the condensing unit before beginning capacitor service, and discharge the capacitor fully before handling terminals, as capacitors retain a lethal charge after power is removed. Verify the MFD ratings and voltage rating of the existing capacitor before installing a replacement, and confirm correct terminal labeling (HERM, FAN, and COM) before making connections. Work should comply with applicable local electrical codes and the equipment manufacturer’s service procedures.
