CMA 3 SERIES

Triphase modular capacitors

The complete range of three-phase capacitors in robust steel cases in order to guarantee a better internal heat dissipation.
All capacitors inside the module are equipped with discharge resistor 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, it 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 S.r.l. declines any responsibility for damage to the condenser, to persons or things deriving from improper or incorrect use of their products.
RoHS Directive MECO condensers are in line with the European directive 2002/95 / EC already known as RoHS directive.
