Single Run Capacitor, Oval, 25/440 uF

Mars 12940 – 25 MFD Oval Motor Run Capacitor, 440V The Mars 12940 is a single-value oval motor run capacitor rated at 25 microfarads (µF) and 440 volts AC. Designed for continuous-duty operation, this component is commonly used in HVAC systems for single-phase induction motors, including blower and condenser fan motors. It supports stable motor performance under varying thermal and electrical loads. Technical Specifications: Capacitance: 25 µF (±6%) Voltage Rating: 440 VAC Frequency: 50/60 Hz Operating Temperature Range: -40°C to +70°C Dielectric: Metallized polypropylene film Case Style: Oval aluminum Case Height: 4-3/4" Overall Dimensions: Approx. 5.25" height × 2.056" width Terminals: 4 quick-connect Non-PCB: Yes Internal Safety Interrupter: Integrated Features: Maintains consistent output in fan motors, air handlers, and similar equipment Designed for systems requiring continuous duty at 440V Compact oval shape for installations with space constraints Built to meet EIA-456A standards for HVAC capacitor performance Suitable for OEM replacement or retrofit where 25 µF / 440V is specified Installation Notes: Before installation, verify that the capacitor's ratings match system requirements. De-energize all circuits and discharge the old capacitor. Use appropriate safety equipment and follow all applicable electrical codes. Installation is recommended to be performed by licensed HVAC personnel.
