Dual Round Multi Capacitor, Universal run capacitor, 55 MFD, 440/370V

Mars 12752 – Jard by Mars 55 MFD, 440V Round Motor Run Capacitor The Mars 12752 is a single-value motor run capacitor designed for continuous-duty applications in HVAC systems. It provides 55 microfarads (MFD) of capacitance with a voltage rating of 440 VAC, making it suitable for use in permanent split capacitor (PSC) motors found in compressors, condenser fans, and air handler blowers. This capacitor is manufactured with a metallized polypropylene dielectric and housed in a round aluminum case. It includes a pressure-sensitive interrupter to protect against rupture and is constructed without polychlorinated biphenyls (PCBs), in compliance with UL and RoHS standards. Technical Specifications Capacitance: 55 MFD (±5%) Voltage Rating: 440 VAC Frequency: 50/60 Hz Case Type: Round aluminum canister Dielectric: Metallized polypropylene film Operating Temperature Range: -40°C to +70°C Safety Feature: Internal pressure-sensitive interrupter Construction: Oil-filled, non-PCB Terminals: ¼" male quick-connect blades Certifications: UL recognized, RoHS compliant Application Overview Intended for PSC motors in residential and light commercial HVAC systems Commonly installed in condenser units, rooftop systems, and other motor-driven equipment Designed to maintain consistent phase shift for improved motor efficiency and reliability Appropriate for service replacement where the original capacitor matches the 55 MFD, 440V specification Installation Guidelines Confirm correct microfarad and voltage ratings prior to replacement Use appropriate personal protective equipment and follow lockout/tagout procedures Discharge the existing capacitor fully before removal Mount using standard brackets; ensure secure electrical connections with proper terminal fit
