Diversitech 4jr0555 Dual Run Capacitor 55/5 Mfd 440V

Product Description

The DIVERSITECH 4jr0555 is a dual run capacitor designed for continuous-duty motor operation in HVAC systems. It combines two capacitance values in a single round metal can, providing start and run support for both the compressor and fan motor in a split-system air conditioner or heat pump. Rated at 55/5 microfarads (MFD) and 440 volts, it operates at 50/60 Hz with a plus or minus 5 percent tolerance. The metal case construction offers durability in the high-heat environment of an outdoor condenser cabinet. Licensed HVAC technicians handle this replacement during seasonal maintenance or when diagnosing weak or failed motor starts.

This capacitor is suited for residential and light commercial HVAC applications where a single dual-rated component replaces two separate run capacitors. It fits inside standard condenser unit capacitor brackets and is a common replacement item for aging or failed OEM capacitors in split-system condensers. The 440-volt rating provides a safety margin above the standard 370-volt systems found in most residential equipment, making it a widely accepted cross-compatible option in the field. The round profile and silver metal case are consistent with OEM form factors used across many condenser platforms.

Key Features

• Dual capacitance rating: 55 MFD and 5 MFD in a single round can
• 440-volt rating suitable for use in standard residential 370-volt and 440-volt systems
• 50/60 Hz operation covers both standard North American and international frequencies
• Plus or minus 5 percent capacitance tolerance for reliable motor performance
• Round metal case construction resists heat and physical damage inside condenser cabinets
• Silver finish round profile matches common OEM capacitor form factors

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 55/5 MFD, 440-volt round capacitor.

Installation Notes

Dual run capacitors are installed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before handling capacitors, as they retain a charge even after power is removed — discharge the capacitor safely before touching terminals. Verify the MFD ratings and voltage rating of the original capacitor before installing a replacement. Follow all applicable local codes and manufacturer wiring diagrams when reconnecting terminals.
