KING COOL capacitor is an electric component that temporarily stores an electrical charge.
A dual "run capacitor" supports two electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor.
It saves space by combining two physical capacitors into one case.
The dual capacitor has three terminals labeled "C", "FAN", and "HERM", which stand for the *C*ommon, Fan, and *HERM*etically sealed compressor.

This capacitor is used for start-up and operation of AC motors with
frequency of 50Hz/60Hz such as Industrial Grade Replacement for
Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and
Compressors. It is small in size, lightweight, heat resisting and anti-explosion.

Dual capacitors come in a variety of sizes, depending on the capacitance (µF or MFD), such
as 40 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt,
as it is build better, but the 370 can't be used in place of a 440 volt. It will work for a while
and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric
to break down and the capacitor to short out. Same as an electric wire- 600V rated wire is
better than 300V one .The capacitance(µF or MFD) must be the same or stay within 10%+ or
5%- of its original value . Example: 50 µF cap can be substituted by 47.5 to 55 µF with the
same or better voltage ratings capacitor .

Round cylinder-shaped dual run capacitors are commonly used for air conditioning,
to help in the starting of the compressor and the condenser fan motor.
Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs
