Description
The Tecumseh K146-52 is a heavy-duty start capacitor engineered to deliver the high-torque starting boost that HVAC compressor motors demand. With a capacitance range of 378–440 MFD and a rated voltage of 125V, this capacitor provides the precise electrical energy surge needed to get compressor motors spinning quickly and efficiently under load.
Key Features
- Capacitance range: 378–440 MFD (microfarads)
- Rated voltage: 125V
- Designed as a genuine Tecumseh OEM start capacitor
- Engineered for reliable high-torque motor starting in HVAC compressor applications
- Helps reduce motor starting current draw and extends compressor life
- Direct replacement for compatible Tecumseh compressor models
Application
Start capacitors are a critical component in single-phase compressor motor circuits. The Tecumseh K146-52 provides the temporary capacitance boost required during motor startup, then drops out of the circuit once the motor reaches operating speed. This protects windings from excessive heat and current, extending the overall service life of the compressor.
