Run Start Capacitor, Round, 60/10 MFD, 440/370

Jard 60/10 µF Dual Run Capacitor – 370/440V, Round Case, Aluminum Construction

The Mars 12796 Jard Dual Run Capacitor is engineered to deliver consistent capacitive power to both compressor and fan motor circuits in HVAC systems requiring dual support. This unit features a dual-section configuration—60 µF and 10 µF—and operates across a dual-rated voltage range of 370/440 VAC, making it suitable for a broad range of residential and light commercial air conditioning equipment.

Designed for continuous-duty applications, the 12796 combines mechanical durability and dielectric stability in a compact form factor. It is widely used by HVAC professionals in service replacements, equipment upgrades, and system retrofits where dual-motor capacitor functionality is required in a single enclosure.
