Rectorseal M11990 Run Capacitor 430-516 Mfd 250V

Product Description

The RECTORSEAL M11990 is a run capacitor rated at 430 to 516 microfarads (MFD) and 250 volts, designed to support motor starting and running performance in HVAC and related mechanical systems. Run capacitors store and release electrical energy to maintain consistent phase shift and torque in single-phase motors. This capacitor is a direct-replacement component typically installed by licensed HVAC technicians during routine maintenance or compressor and blower motor service calls. Its compact cylindrical form factor fits standard capacitor mounting brackets used across a wide range of residential and light commercial equipment.

This capacitor is suited for use in systems where a high-MFD run capacitor is required to support large single-phase motors. The 250-volt rating accommodates standard single-phase residential and light commercial power supplies. Typical applications include compressor motor support and fan motor circuits in HVAC equipment. The unit measures 1.812 inches wide by 4.375 inches tall, making it compatible with standard bracket-mount installations in condensing units and air handling cabinets.

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase motor applications in residential and light commercial HVAC systems requiring a 430 to 516 MFD, 250-volt capacitor.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, as capacitors retain a charge even after power is removed and must be safely discharged before handling. Follow NEC guidelines and local electrical codes when replacing capacitors in energized equipment enclosures. Verify capacitance rating and voltage match the equipment nameplate specifications before installation.
