Hartland Controls tp-cap-45/7.5/440r Dual Run Capacitor

Product Description

The HARTLAND CONTROLS tp-cap-45/7.5/440r is a dual run capacitor rated at 45 plus 7.5 microfarads (MFD) and 440 VAC, housed in a round aluminum case. Run capacitors maintain the phase shift needed to keep single-phase PSC motors running efficiently after startup. This unit serves both the compressor winding and the fan motor winding simultaneously, eliminating the need for two separate capacitors. It is built with aluminum oil-filled construction and manufactured in accordance with UL 810 and EIA standard RS-456, making it a code-compliant replacement for residential and light commercial HVAC service work.

This capacitor is suited for split-system air conditioners, heat pumps, and packaged units that use a single dual-rated round capacitor to support both the compressor and condenser fan motor. The round case design fits most standard capacitor mounting brackets found in outdoor condensing units. Licensed HVAC technicians typically install this part during seasonal maintenance calls, capacitor failure diagnostics, or compressor replacement jobs where the existing capacitor is found to be out of tolerance.

Key Features

• Dual-rated 45 MFD plus 7.5 MFD in a single round capacitor — replaces two separate units
• 440 VAC rating provides compatibility with both 370 VAC and 440 VAC application requirements
• Aluminum oil-filled construction for thermal stability and long service life
• Round case fits standard condenser unit capacitor brackets
• Manufactured to UL 810 and EIA RS-456 standards for code-compliant installation

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners, heat pumps, and packaged HVAC units requiring a 45/7.5 MFD, 440 VAC round capacitor.

Installation Notes

Dual run capacitors must be installed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit before servicing capacitors — stored charge can remain even after power is removed, so discharge the capacitor safely with an approved discharge tool before handling. Verify the MFD ratings and voltage rating of the replacement match the equipment nameplate before installation. Follow NEC and local electrical code requirements for disconnect and wiring practices.
