Product Overview
Start capacitors are a critical component in single-phase compressor motors. They remain in the circuit only during the startup phase, providing the extra phase shift and torque needed to bring the motor up to operating speed. Once the motor reaches run speed, the start capacitor is switched out of the circuit by a relay or potential relay. Using the correct MFD range and voltage rating — such as the 324–389 MFD / 165V specification of the K146-55 — ensures reliable starts and protects the compressor motor from stress and premature failure.
