Dual Run Capacitor, Round, 55/7.5/440 uF

Mars 12793 – Jard Dual Run Capacitor, 55/7.5 MFD, 370/440V, Round Case The Mars 12793 capacitor from the Jard product line is a dual-rated motor run capacitor used in HVAC systems where both the compressor and fan motor are powered by a single component. Rated for 55/7.5 microfarads at 370/440 volts AC, this capacitor supports permanent split capacitor (PSC) motors found in air conditioning condensers and heat pump applications. The capacitor is constructed with metallized polypropylene film and enclosed in an oil-filled aluminum case. It includes an internal pressure interrupter for enhanced safety and meets industry standards for continuous-duty service in residential and light commercial HVAC equipment. Specifications Model Number: 12793 Capacitance: 55/7.5 µF ±5% Voltage Rating: 370/440 VAC Frequency: 50/60 Hz Operating Temperature: -40°C to +70°C Enclosure: Round aluminum case, hermetically sealed Terminals: ¼" quick-connect Dielectric: Metallized polypropylene film, non-PCB Height: Approx. 5-1/4 in. Diameter: 2 in. Application Use Dual-run design supports both compressor and fan motor circuits Intended for PSC motors in standard HVAC units including split system condensers and rooftop units Suitable for service replacements where the original specification matches capacitance and voltage Installation Notes Only qualified HVAC professionals should perform installation Disconnect power at the breaker and confirm voltage is zero before handling Use an appropriate mounting bracket to reduce vibration during operation Verify correct terminal connections: "C" (common), "HERM" (compressor), "FAN" (fan motor) Test the capacitor prior to commissioning using a calibrated multimeter with capacitance function Advantages for Contractors Combines two capacitors in one housing, reducing component count and installation time High-voltage capability enhances reliability in systems prone to line fluctuations Compact round profile for compatibility with most OEM brackets UL recognized and RoHS compliant for assured quality and environmental standards
