Description
Mars 12986 Oval Dual Run Capacitor — 40/5 MFD, 440VAC
The Mars 12986 is a heavy-duty oval dual run capacitor engineered to keep residential and commercial HVAC systems running at peak efficiency. Rated at 40/5 microfarads and 440 VAC, this single capacitor simultaneously supports both the compressor motor and the condenser fan motor — eliminating the need for two separate capacitors and simplifying service calls.
Key Specifications
- Capacitance: 40/5 MFD (Microfarad)
- Voltage Rating: 440 VAC
- Shape: Oval
- Type: Dual Run Capacitor
- Brand: Mars (Motor & Armature)
- SKU: 12986
Features & Benefits
- Dual-section design powers both the compressor (40 MFD) and fan motor (5 MFD) from a single unit
- 440 VAC rating provides a wide safety margin for standard 370 VAC and 440 VAC HVAC applications
- Oval form factor fits a broad range of equipment cabinets and mounting configurations
- Built to Mars’ stringent quality standards for long service life and consistent capacitance
- Direct replacement for failed or degraded dual run capacitors in air conditioners and heat pumps
Application
The Mars 12986 is ideal for HVAC technicians servicing residential and light-commercial air conditioning systems, heat pumps, and condensing units. A properly functioning run capacitor is critical to motor starting torque, running efficiency, and overall system longevity. Replacing a weak or failed capacitor with the Mars 12986 can restore proper operation and prevent compressor or fan motor burnout.
