The Titan Pro TRCFD405 Capacitor is a dual rated motor run capacitor. A capacitor is a component that stores electrical energy for you motor to operate. The capacitance or storage is reported in microfarads (uF or mFd).
There are three types of capacitors - start, run and dual run. A start capacitor only runs while your unit is starting and shuts off immediately. As the name implies, a run capacitor runs constantly, providing constant voltage and current adjustments to the motor. A dual run capacitor, like the TRCFD405, is most frequently used in air conditioners. A dual run capacitor is a single capacitor that incorporates the functions of 2 run capacitors. It will support both the compressor motor and condenser and will have 2 MFD ratings (compressor is the higher rating and the fan is the lower). A dual capacitor has 3 terminal banks (power, fan and herm - compressor) on the top and is typically round, but can be oval as well. The shape is not as important as the capacitor specifications fulfilling your requirements needed AND fitting in the space!
The TRCFD455 is a dual rated, round capacitor and will provide:
- Up to 60,000 hours of operational life
- 40 + 5 mFd
- 370/440 Voltage
- Built to EIA-456-A and IEC 60252-1:2001 standards
Confirm that the voltage ratings meet or exceed what is required by your equipment AND the mFd ratings match both the fan motor and the compressor.
