120µF (120uF) 250VAC Motor Start Capacitor | E348072 | 61B1D250120NNCA

What does a 120µF motor start capacitor do?
A 120µF start capacitor provides the initial electrical boost required to start a single-phase electric motor. It helps generate the torque needed to overcome inertia and start the motor smoothly.

Where is a 120µF start capacitor commonly used?
120µF start capacitors are commonly used in air compressors, water pumps, HVAC systems, and refrigeration equipment where strong starting torque is required.

What happens if a 120µF start capacitor fails?
If the capacitor fails, the motor may hum without starting, struggle under load, or trip circuit breakers due to increased current draw.

Can I replace a 120µF capacitor with a different µF rating?
No. Always replace the capacitor with the same microfarad (µF) rating and voltage specification to ensure proper motor performance and avoid damage.

What is the difference between a start capacitor and a run capacitor?
Start capacitors are used only during motor startup to provide high starting torque, while run capacitors remain in the circuit during normal operation to improve efficiency.

How can I tell if my start capacitor is faulty?
Common signs include a motor that hums but won’t start, slow or inconsistent startup, overheating, or repeated tripping of electrical protection devices.
