GENERAL INFORMATION
The capacitors generally defined as motor capacitors are used for the start up and running
of single-phase induction 2 and 3 windings motors.
The capacitance of these capacitors (permanent connection) must be carefully established
to avoid possible overheating of the auxiliary winding.
Construction peculiarities
For the construction of these capacitors a polypropylene film dielectric is used, metallised in a vacuum,
self-healing that allows the obtaining of capacitive units with very low losses and reduced
overall dimensions. These elements are subsequently encapsulated in plastic case
and then incorporated in resin.

WARNINGS
Improper use of the capacitor such as, for example, applications that involve exceeding the capacities and/or characteristics reported on a given capacitor, can cause an irreversible breakdown and/or breakage that can occur with the explosion of capacitor or with a deterioration such as to manifest loss of capacity, increase of power factor and permanent circuit interruption. Meco Capacitors declines any responsibility for damage to the capacitors, to persons or things deriving from improper or incorrect use of their products.
