Run Start Capacitor, Round, 60/5 MDF, 440/370

JARD 60/5 µF Dual Run Capacitor – 440/370V, Round Aluminum Case

The Mars 12794 JARD Dual Run Capacitor is designed to deliver consistent capacitive power to both compressor and fan motors in single-phase HVAC systems. With a 60/5 microfarad rating and a 440/370 VAC voltage tolerance, this round dual capacitor is engineered for reliability under high-start and continuous-duty conditions.

Built with metallized polypropylene film and housed in a sealed aluminum canister, the 12794 model provides dependable performance across varying environmental exposures. Its dual-terminal design consolidates two capacitive loads into a single component, reducing parts inventory and simplifying installation in the field.
