Dual Run Capacitor, Round, 25/5/440 uF

Mars 12778 – Dual Run Capacitor, 25/5 MFD, 370/440V, Round The Mars 12778 is a dual-section motor run capacitor with capacitance ratings of 25 µF and 5 µF, designed for use in single-phase HVAC systems requiring both compressor and fan motor operation. This capacitor supports continuous duty and provides phase shift to improve the efficiency and power factor of permanent split capacitor (PSC) motors. Technical Specifications: Capacitance: 25 µF (HERM) / 5 µF (FAN) Voltage Rating: 370/440 VAC Frequency: 50/60 Hz Shape: Round aluminum can Terminal Configuration: 3-tab quick-connect (C, FAN, HERM) Height: 4-1/8 inches Diameter: 2 inches Operating Temperature Range: -40°C to +70°C Dielectric: Metallized polypropylene film Internal Protection: Pressure-sensitive interrupter Environmental Compliance: Non-PCB Standards: Meets EIA-456A performance requirements Application: Suitable for air conditioning condensers, heat pump outdoor units, and other PSC motor systems that require dual capacitance values. Provides consistent phase angle for both compressor and fan motors, enhancing motor efficiency and stability under load. Rated for use in demanding environments and temperature extremes. Installation Notes: Replacement must match capacitance and voltage ratings. Ensure power is disconnected and stored energy is safely discharged prior to installation. Use insulated tools and observe all local electrical codes. Installation by qualified HVAC technicians is recommended for proper system integration.
