Tecumseh K146-18 Capacitor 378-440 MFD 165V

The Tecumseh K146-18 Capacitor operates as a high-performance start capacitor for electric motor startup in HVAC systems, which primarily serve air conditioners, heat pumps and refrigeration units. The capacitor's operating range extends from 378 to 440 MFD and it handles voltages up to 165V to deliver the torque needed for motors to start despite inertia. The Capacitor used residential and commercial HVAC equipment by operating and similar compressor models. The capacitor improves motor efficiency and cuts startup power consumption while protecting compressors through pressure control and heat regulation.
