Metal case motor run capacitors

Capacitor equipped with “overpressure” safety device S2 protection class, in aluminium case.

 

For the useing 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 running capacitors have VDE approval mark in compliance with the European Standards EN60252-1.

We show below the life rating of the operating classes :

Class D = 1.000 hours
Class C = 3.000 hours
Class B = 10.000 hours
Class A = 30.000 hours

40 means -40°C, minimum operating temperature
085 means +85°C, maximum operating temperature
21 = duration (days) of the damp-heat test
