Mars 12786 40/5 MFD 440VAC Round Dual Run Capacitor

Description

Mars 12786 40/5 MFD 440VAC Round Dual Run Capacitor

The Mars 12786 is a round dual run capacitor rated at 40/5 microfarads and 440 VAC, engineered to deliver dependable starting and running performance for residential and light commercial HVAC systems. Dual run capacitors combine two capacitors in a single compact housing, simultaneously supporting both the compressor and the condenser fan motor — reducing component count and simplifying installation.

Key Features

• Capacitance: 40/5 Microfarad (µF) — dual section for compressor and fan motor
• Voltage Rating: 440 VAC
• Round housing for easy, space-saving installation
• Dual run design eliminates the need for two separate capacitors
• Built to withstand the demanding thermal and electrical cycles of HVAC operation
• Compatible with a wide range of residential and light commercial air conditioning and heat pump systems

Why Choose a Dual Run Capacitor?

Dual run capacitors maintain the phase shift needed to keep both the compressor and fan motor running efficiently after startup. A failing capacitor is one of the most common causes of HVAC system breakdowns — replacing it promptly with a quality Mars unit helps restore full system performance and extend equipment life.
