PhMKP...Cylindrical Aluminum

Vishay ESTA

ESTAprop/ESTAdry Power Factor Correction

Capacitors Low Voltage

CAPACITORS IN CYLINDRICAL ALUMINUM CASING

APPLICATION

3-PHASE CAPACITOR,

SCREW-TYPE TERMINALS

ESTAprop PhMKP-type capacitors in cylindrical aluminum

casing have been designed for Power Factor Correction in

low voltage plants. Loads as motors and transformers

consume real power as well as reactive power. Generators,

supply cables, and other electrical distribution equipment

should be relieved from reactive power.

ESTAprop capacitors may be used for:

• automatic PFC-equipment

• individual fixed PFC (e.g. motors, transformers, lighting)

• group fixed PFC

• tuned and detuned capacitor banks

• harmonic trap (e.g. UPS, frequency drives, converter)

3-PHASE CAPACITOR,

PUSH-ON TYPE TERMINALS

DESIGN

The ESTAprop MKP capacitor is a metallized polypropylene

film capacitor with self-healing properties. The current

carrying metal layer of an MKP capacitor is vaporised onto

one side of the polypropylene film. The front surface of

tubular winding elements are joined by means of the metal

spray method (schooping). Three winding elements are

encapsulated in one aluminum casing and connected to form

a true 3-phase capacitor. The overpressure tear-off fuse

prevents the capacitor from bursting at the end of service life,

or due to inadmissible electrical or thermal overloads.

1-PHASE CAPACITOR,

PUSH-ON TYPE TERMINALS

The assembly is impregnated with a natural oil (fire point

> 300 °C) under vacuum and hermetically sealed. This

construction method ensures excellent heat dissipation and

constant capacitance over an extended period of time.

The capacitor is housed in a tubular aluminum container with

a metal lid press-rolled onto it. The current is supplied via

screw-on (M5) or push-on (6.3 x 0.8 mm) connectors. A

threaded stud (M12) at the bottom of the container serves for

both grounding and mounting.

ESTAprop and ESTAdry capacitors will be delivered

together with discharge resistors and hardware for mounting

and connection.

THICK FILM DISCHARGE RESISTOR UNIT

Vishay ESTA standard capacitors of 84.4 mm diameter will

come with a THICK FILM DISCHARGE RESISTOR UNIT,

forked terminals for easy mounting and IN-LINEconnection

of the capacitors to the supply.

Capacitors are in accordance with protection class IP00. For

all types, plastic covers for a higher degree of protection are

available.
