Rectorseal m14033 Run Capacitor 12.5 Mfd 370 440V

Product Description

The RECTORSEAL m14033 is a single-run capacitor rated at 12.5 microfarads (MFD) and dual-rated for 370 and 440 volts, housed in an oval case. Run capacitors provide continuous phase-shifted current to the start and run windings of single-phase AC motors in HVAC equipment, keeping compressors and fan motors operating at rated efficiency. This unit is manufactured in the USA and includes a physical interrupter, a safety feature that helps interrupt internal fault conditions. HVAC technicians install this capacitor during compressor or condenser fan motor replacements and as a direct swap when a failed capacitor is confirmed by capacitance meter testing.

This capacitor is suited for residential and light commercial HVAC applications where single-run capacitors are required. Typical install scenarios include replacing a failed run capacitor on a condenser unit fan motor or compressor. The oval form factor fits standard capacitor brackets found in most condensing units. The dual voltage rating of 370 and 440 volts provides flexibility across a range of equipment voltage specifications.

Key Features

• 12.5 MFD capacitance for precise motor run support
• Dual-rated for 370 and 440 volts for broad equipment compatibility
• Oval case fits standard condenser unit capacitor mounting brackets
• Physical interrupter safety feature helps manage internal fault conditions
• Manufactured in the USA

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase compressor and condenser fan motors requiring a 12.5 MFD 370 or 440 volt oval run capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before handling capacitors, as run capacitors store a lethal charge even after power is removed — always discharge the capacitor using an approved discharge tool before handling. Verify the replacement capacitor MFD rating and voltage rating match or exceed the original equipment specification before installing. Secure the capacitor firmly in the mounting bracket and ensure all terminals are tightly connected.
