MARS 11987 Round Start Capacitor 340-408 MFD 250/220V

The MARS 11987 Round Start Capacitor 340-408 MFD 250-220V is an electrical component that is installed in HVAC systems to provide a high burst of stored energy to assist compressors and motors in starting. It is installed in air conditioners, heat pumps, and refrigeration units, where it momentarily raises the torque to assist the compressor and other parts of the motorized system to overcome initial inertia. The start capacitor is turned off when the motor is running, and this is aimed at starting the motor and reducing the stress on the electrical and mechanical parts.
