Hartland Controls tp-cap-40/7.5/440r Dual Run Capacitor

Product Description

The HARTLAND CONTROLS tp-cap-40/7.5/440r is a dual-rated motor run capacitor designed for use in single-phase HVAC systems where both the compressor and fan motor require capacitive support from a single unit. Rated at 40/7.5 microfarads (MFD) and 440 VAC, this round-case capacitor uses aluminum oil-filled construction, delivering stable capacitance under continuous-duty load. It is manufactured in accordance with UL 810 and EIA standard RS-456, making it a code-compliant choice for licensed HVAC technicians performing compressor or condenser fan motor service.

This capacitor is suited for residential and light commercial air conditioning systems where a single round dual-run capacitor replaces separate compressor and fan capacitors. The 40 MFD section supports the compressor motor start winding, while the 7.5 MFD section serves the condenser fan motor. The round case format fits standard capacitor mounting brackets found in most condensing unit electrical compartments. Technicians replacing failed run capacitors due to bulging, low-capacitance readings, or start failure will find this a direct-form-factor replacement.

Key Features

• Dual-rated: 40 MFD for compressor, 7.5 MFD for condenser fan motor
• 440 VAC rating provides compatibility across both 370 VAC and 440 VAC applications
• Round aluminum oil-filled case for continuous-duty motor run service
• Manufactured to UL 810 and EIA RS-456 standards
• Replaces separate single capacitors with one compact dual-run unit

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 40/7.5 MFD, 440 VAC round-case capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit before servicing the capacitor, and discharge the existing capacitor fully before handling — stored charge can cause serious injury even after power is removed. Verify the MFD ratings and voltage rating of the replacement match the nameplate specifications of the equipment. Secure the capacitor in its mounting bracket and confirm all terminals are fully seated before restoring power.
