Diversitech 4jr0530 Dual Run Capacitor 30+5 Mfd 440V

Product Description

The DIVERSITECH 4jr0530 is a round dual run capacitor rated at 30+5 microfarads (MFD) and 440 volts AC, housed in a metal case. Dual run capacitors serve two motor windings simultaneously — typically the compressor and the condenser fan motor — within a single unit. This capacitor maintains the phase shift needed to keep induction motors running efficiently after startup. The metal case provides durability in outdoor and high-temperature equipment environments. Rated for both 50 Hz and 60 Hz operation, it suits a wide range of HVAC equipment. Licensed HVAC technicians install this component during routine capacitor replacement or system failure diagnosis.

This capacitor is used in residential and light commercial air conditioning and heat pump systems where a single capacitor must serve both the compressor and the fan motor. It is a common replacement item during summer service calls when heat and run-time hours cause capacitor degradation. The round form factor fits standard capacitor brackets and mounting hardware found in most condensing unit cabinets. A tolerance rating of plus or minus 5 percent keeps motor performance within acceptable operating range.

Key Features

• Dual capacitance rating of 30+5 MFD serves compressor and condenser fan motor from one unit
• 440-volt AC rating provides compatibility with both 370-volt and 440-volt rated systems
• Round metal case measures 3.54 inches in height for standard bracket fitment
• Plus or minus 5 percent capacitance tolerance ensures consistent motor performance
• Rated for 50 Hz and 60 Hz operation

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial air conditioning and heat pump condensing units requiring a 30+5 MFD, 440-volt round capacitor.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Disconnect and lock out all power to the condensing unit before opening the electrical panel. Capacitors store a charge even after power is removed — discharge the capacitor safely using an appropriate resistor tool before handling terminals. Follow local codes and the equipment manufacturer's wiring diagram when connecting the replacement capacitor.
