MKP Series
METALLIZED POLYPROPYLENE FILM CAPACITOR
MOTOR RUN CAPACITORS
Loose
Taped
Typical applications: The capacitor is used in series to the
auxiliary winding of a singleꢀphase electric motor, allowing it
to start and increase its torque while working. The capacitor
is particularly suitable for applications requiring reduced
dimensions i.e. airꢀfans and circulators.
