90MF 450V CAPACITOR mm55

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 self-extinguishing plastic 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 and ASEV approvals in accordance with European Standard EN 60252.

We show below the life rating of the operating classes :

Class D = 1000 hours
Class C = 3000 hours
Class B = 10000 hours
Class A = 30000 hours

25 = -25°C minimum working temperature
085 = +85°C maximum working temperature
21 = duration (days) of the humidity test.
RPN = capacitors with fast-on terminals
