MFR-4 series

MFR-4 capacitors are equipped with the “overpressure” safety device S2 protection class, in aluminium case.
For use in running single-phase asynchronous motors and in all general a.c. applications at 50/60Hz, ITALFARAD proposes a range of self-healing capacitors, manufactured using a aluminium case filled with resin. This range gives very good electrical reliability together with high mechanical resistance to shock and vibration.
All ITALFARAD motor capacitors have VDE approval in compliance with the European Standard EN 60252-1.
The life rating of the operating classes are listed below:
Class D = 1000 hours
Class C = 3000 hours
Class B = 10000 hours
Class A = 30000 hours
40 = -40°C Minimum operating temperature
085 = +85°C Maximum operating temperatue
21 = Damp heat test term (days) for temperate climates.
