What are the rated breaking and making currents for a general purpose switch according to IEC 62271-103?
A general purpose switch shall have specific ratings for each switching duty as follows:
• rated mainly active load-breaking current equal to the rated normal current;
• rated distribution line loop-breaking current equal to the rated normal current;
• rated cable-charging breaking current as shown in Table 1;
• rated line-charging breaking current as shown in Table 1;
• rated short-circuit making current equal to the rated peak withstand current;
and additionally for switches intended to be used in non-effectively earthed neutral
systems:
• rated earth fault breaking current;
• rated cable- and line-charging breaking current under earth fault conditions.
• rated mainly active load-breaking current equal to the rated normal current;
• rated distribution line loop-breaking current equal to the rated normal current;
• rated cable-charging breaking current as shown in Table 1;
• rated line-charging breaking current as shown in Table 1;
• rated short-circuit making current equal to the rated peak withstand current;
and additionally for switches intended to be used in non-effectively earthed neutral
systems:
• rated earth fault breaking current;
• rated cable- and line-charging breaking current under earth fault conditions.
