Series MW

Application: Motor-run capacitors, especially designed for Fans. Otherwise suitable for all single-phase AC loads such as Coolers and other small appliances.

Container: Cylindrical containers made up of aluminium.

Encapsulation: Dry filling material (Non-P.C.B resin).

Conforming to: IEC 60252-1, ISO 9001:2015 and JISC-4908.

Rated Volts: 400V – (For other voltages please enquire).

Rated Frequency: 50/60Hz.

Capacitance Range: 2.5, 3.5, 4.5 µF. (For others, please enquire).

Tolerances: ±10% 

NOTE: Capacitors are wrapped in heat shrink sleeve to minimize the effect of external temperature on capacitors and also useful for internal heat dissipation.

APPLICATION:  Specially designed for fans and also suitable for other single phase AC loads.

CONSTRUCTION:  The capacitor elements are formed by winding low loss, self healing, metallized polypropylene film. High speed
computerized winding machines are used for this purpose. The film tension is maintained at a constant value
throughout the winding process thereby totally excluding air from the winding.

CONTAINER:  Cylindrical container made up of aluminium, wrapped in heat shrink sleeve. Heat shrink sleeve is useful for internal heat dissipation and minimize the effect of external temperature on capacitor.
