CNC Low Voltage Self-healing Shunt Power Capacitor YC111-B

Technical Data

YC111 capacitors allow power factor correction installations to be constructed for any requirement and meet standard, EN 60831-4 and-2 as well as IEC 831-1 and 2.

Mechanical Construction

Cylindrical aluminium case, dielectric consisting of metallized polypropylene foil.Dry type, filed with resin.The dielectric is self-healing. In case of a breakdown caused, for example, by voltage overload, the self-healing effect takes place.If the self-healing process does not operate (e.g because of voltage, current or thermal overload) the cover plate, which is designed as an overload valve, is raised and ruptures the internal connecting wires to the coils, so that the capacitor is disconnected from the mains.

Discharging

According to IEC 831, every power capacitor must have a discharge device which guarantees a discharge to 75Vac within three minutes.HY capacitors have discharge resistors which guarantee discharge to 50VAC with in one minute.
