Mars M12710 Run Capacitor 15 Mfd 370 Volt Round

Product Description

The MARS M12710 is a single-run capacitor rated at 15 microfarads (MFD) and 370 volts, designed for use in single-phase AC motors found in HVAC equipment. Run capacitors maintain a continuous phase shift in the motor winding to keep the motor running efficiently after startup. The M12710 uses a round form factor, which is the standard housing style for most residential and light-commercial HVAC applications. Licensed HVAC technicians install this capacitor as part of routine capacitor replacements on condenser fan motors and compressors.

This capacitor is suited for residential and light-commercial HVAC systems where a single-run capacitor is required on a condenser fan motor or other single-phase motor load. The round housing fits standard capacitor brackets and mounting straps common in outdoor condensing units. It is also noted as a replacement for MAR-12910, making it relevant for technicians cross-referencing older part numbers in the field. The 370-volt rating is appropriate for standard residential line-voltage motor circuits.

Compatibility

Listed as a replacement for MAR-12910. Designed as an OEM-style replacement run capacitor for single-phase condenser fan motors and compressor circuits in residential and light-commercial HVAC equipment requiring a 15 MFD, 370-volt round capacitor.

Installation Notes

Capacitor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before handling capacitors, as they store a lethal charge even after power is removed — discharge the capacitor through a resistor before touching terminals. Verify the MFD rating and voltage rating of the original capacitor before installing the replacement. Follow all applicable local electrical codes and the equipment manufacturer's service instructions.
