A capacitor is an electric component that temporarily stores an electrical charge.
Ombines two capacitors into one unit.
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 on the top labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line.
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.
Technical Specification
Capacity: 45uf + 5uf
Tolerance: ±6%
Shape: Round Run
Rated voltage: AC 370-440V
Frequency: 50/60 Hz
Safety rated: 10,000 AFC
Operating temperature: -40°C to +70°C/ -13℉ to 158℉
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 capacitors rated voltage will cause the dielectric to break down and the capacitor to short out.The capacitance(μF or MFD) must be the same or stay within 10%+ or 5%- of its original value . But use the same voltage ratings capacitor is better.
Remark:
1.Please wait for at least 1 minute to let capacitor to release power before replacement
2.Most common of capaictor broken is that condensor motor not work, capacitor become fatter obviously than before
