Application:
- MKP capacitors 471 are determined for start and operation of single phase or three phase asynchronous motors, which are single phase energized. They can operate in permanent operations as run capacitors.
Electrical properties:
- Nominal capacitance: 2 to 60 µF
- Tolerance of capacitance: ± 10% ( K ) , ± 5% ( J )
- Nominal voltage: Un 480 Vac 50Hz
- Test voltage between terminals: 2 x Un 50Hz / 60s
- Test voltage between terminals and case: 2000V 50Hz / 60s
Type marking of capacitors:
1st letter indicates type of terminals
- J . . . single faston tag 6,3 x 0,8 mm
- D . . . double faston tag 2 x 6,3 x 0,8 mm (except Ø D = 30 mm)
- E . . . soldering tags without a discharging resistor
- K . . . outlet cable with pressed protective cap
2nd letter indicates case fixing system
- B . . . case without a base stud
- S . . . case with a base stud M8 x 10mm (a nut and a washer are included)
Example of marking for an order:
- TM 471 JS 20 µF ± 5 % - motor capacitor for start and operation of single phase or three phase asynchronous motors in an aluminium case with a base stud, outlets are made with single faston tags. Capacitance is expressed in µF with tolerance ±5 %.
