Mars 12778 Dual Run Capacitor 25+5 MFD 440V Round

The Mars 12778 is a professional-grade dual run capacitor designed for HVAC systems and air conditioning applications. This round metal capacitor features a dual rating of 25+5 microfarads (μF) at 440 volts AC, making it ideal for simultaneously powering both compressor and fan motors in residential and commercial cooling equipment.

Key Features:

• Dual capacitance rating: 25 μF + 5 μF for compressor and fan motor operation
• 440 VAC voltage rating for reliable performance in demanding applications
• Round metal housing for durability and heat dissipation
• Three terminal configuration (C, HERM, FAN) for easy wiring
• Moisture-resistant construction for extended service life
• Meets industry standards for HVAC replacement capacitors

This dual run capacitor eliminates the need for separate compressor and fan capacitors, simplifying installation and reducing equipment space requirements. The Mars 12778 is a direct replacement for OEM capacitors with matching specifications and is commonly used in air conditioners, heat pumps, and condensing units. Always verify capacitance and voltage ratings match your equipment specifications before installation.
