TRADEPRO 45+5 MFD 370/440 VAC Round Dual Run Capacitor TP-CAP-45/5/440R-A

The TRADEPRO TP-CAP-45/5/440R-A is a high-quality dual run capacitor designed for reliable performance in HVAC systems. It provides the dual capacitance needed to support both the compressor (HERM) and fan motor in air conditioners, heat pumps, and similar equipment. Built to OEM standards, it is UL-recognized, meets EIA-456-A requirements, and is protected to 10,000 AFC for safety and durability.

Key Features

• Dual capacitance rating of 45 + 5 MFD (µF)
• Dual voltage rating: 370/440 VAC (suitable for systems requiring either voltage)
• Round aluminum case construction
• Quick-connect terminals (typically labeled C, HERM/H, and FAN/F)
• Operates at 50/60 Hz
• ±3% capacitance tolerance (industry-standard tight tolerance)
• Operating temperature range: –40°C to +70°C (–40°F to 158°F)
• Long service life design (typically rated for 60,000 hours at rated temperature)
• Vacuum-sealed construction to minimize leaks and contamination
• UL/CSA recognized and tested per EIA-456-A standards

Benefits

• Restores proper motor starting and running performance for both compressor and condenser fan
• Dual voltage rating offers flexibility—higher-voltage (440V) units can safely replace 370V capacitors in compatible applications
• Reliable OEM-quality construction helps reduce callbacks and premature failures
• Compact round design fits standard mounting brackets in most residential and light commercial units
• Easy drop-in replacement for many common dual-run capacitors of matching ratings
• Enhanced safety features (pressure-sensitive interrupter protection in many equivalent designs)

Specifications

Dimensions

• Diameter: approximately 2.46 in (2-7/16 in / ~62.5 mm)
• Height/Length: approximately 4.41 in (4-7/16 in / ~112 mm)
• Overall package size is compact for standard HVAC capacitor mounting locations. Always verify fit against the existing unit before installation.

Compatibility

This is a direct replacement for many dual-run capacitors with matching 45/5 MFD and 370/440 VAC ratings. Common cross-references include (but are not limited to):

• TP-CAP-45/5/440R
• 27L889 / 27L889BX
• C4455R / C3455R
• 97F9851 / 97F9895 series
• TRCD455 / TRCFD455 / PRCFD455
• Various GE/Genteq, Capcom, and other OEM/aftermarket equivalents

It is commonly used in residential and light-commercial air conditioning condensers, heat pumps, and package units that require a dual-run capacitor for the compressor and outdoor fan motor. Always confirm the exact capacitance, voltage, and physical dimensions of the original capacitor before replacement. Shape (round vs. oval) primarily affects mounting; electrical ratings must match.

Note: Installation should be performed by a qualified HVAC technician. Discharge the old capacitor safely before removal, and match wiring to the terminal labels (C = Common, HERM = Compressor, FAN = Fan).
