PROTECTION CLASS: S3
WHY MB PROTECTED S3 CAPACITORS:
A safety listing is not required for motor run capacitors under IEC 60252-1 but listing for a(P-2 used in old standards for all protected capacitors, now S2 is used for pressure interrupter and S3 for segmented film capacitors) S3 motor run capacitor requires an interrupter system by segmented film ensuring the capacitor fails in an open condition in the event of a capacitor failure. Otherscapacitors, listed as (P0,P1) S0 and S1 may or may not fail in an open condition.
For film capacitors with very high standards for stability and long lifetime, such as S3 capacitors, the metallization can be made with a special fault isolation pattern. Such a metallization formed into patterns. Each of these patterns” produces a deliberately narrowed cross-section in the conductive metallization. These restrictions work like microscopic fuses so that if a point-defect short circuit between the electrodes occurs, the high current of the short only burns out the fuses around the fault. The affected sections are thus disconnected and isolated in a controlled manner, without any explosions surrounding a larger short-circuit arc. Therefore, the area affected is limited and the fault is gently controlled, significantly reducing internal damage to the capacitor, which can thus remain in service with only an infinitesimal reduction in capacitance.
