metalized polypropylene film capacitor / module / power / three-phase
metalized polypropylene film
The MCTN series three-phase capacitors are obtained by assembling single-phase capacitors. They are made with self-healing metallic polypropylene and impregnated with a non-toxic, biodegradable resin (NO PCB). Each element is contained by a casing with an over-pressure protection device, triggered in case of non-recoverable failure. Each capacitor is fitted with a discharge resistor to reduce the residual capacitor voltage to less than 75V in 3 minutes, as per CEI EN 60831 standards. MCTN capacitors are fitted with induction coils to limit the current peaks generated when power is applied to the capacitor.
