Run Capacitor, Oval, 70 MFD, 440V

Mars 12830 – 70 MFD 440V Oval Motor Run Capacitor The Mars 12830 motor run capacitor is rated at 70 microfarads (MFD) and 440 VAC, designed for continuous-duty operation in single-phase induction motors. This oval metal case capacitor is typically used in HVAC applications where reliable, sustained power is required for fan motors, blowers, and compressors. Built for demanding operating environments, it features an oil-filled, non-PCB design and includes an internal pressure-sensitive interrupter for safety compliance. Technical Specifications Capacitance: 70 µF (microfarads) Rated Voltage: 440 VAC Frequency: 50/60 Hz Case Shape: Oval Case Material: Aluminum Dielectric Fluid: Non-PCB, oil-filled Safety Feature: Internal pressure interrupter Operating Temperature Range: -40°C to +70°C Terminals: Standard dual quick-connect Application Suitable for use in permanent split capacitor (PSC) motor circuits Commonly used in HVAC blower motors, condenser fans, and other air-moving equipment Compatible with systems designed for 440V capacitors in residential and light commercial settings Installation Notes Verify that the replacement capacitor matches the OEM specifications for capacitance and voltage. Power must be disconnected and the old capacitor safely discharged before removal. Mount the new unit securely, and ensure all terminal connections are tight and appropriately insulated. For best results, installation should be completed by a licensed HVAC technician following local electrical code requirements.
