Application
Start capacitors like the Mars 11953 are used to provide the extra electrical push required to initiate motor rotation. Once the motor reaches operating speed, the start capacitor is switched out of the circuit — making correct capacitance and voltage ratings critical for both motor protection and longevity. Always verify motor nameplate data before selecting a replacement capacitor.
