Note :

1) It should be noted that presence of harmonics produces over voltage & over current on capacitors. Resonance may

cause serious damage to installation if a siginificant level of total harmonic distortion level exists for voltage or current.

In such cases, series reactors must be considered.

2) Operating temperature class: In accordance with the reference standards, these temperatures are those measured on

the surface on the capacitor

Approved marks

(1) Currently available from Icotron and EIPL.

(2) Homologation in process

EN 60252

250(2), 400(1) and 450(1) Vac.
