CMI4 Series

Metallized polypropilene film single phase motor capacitors

condensatori monofase cmi4

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 high  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, 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.
