Complete range of three-phase capacitors with cylindrical-shaped casing. Particularly suitable for fixed power factor correction, whenever there are problems of dimensions.
All capacitors are equipe with external discharge resistor, over-current fuses and overpressure safety device that, in the event of the element failing, disconnects it fromthe power circuit ensuring the maximum safety in every application.

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.
